7 daysInput: atkbd - skip deactivate for Lenovo IdeaPad Slim 3 15IWC11Martino Papero
The internal keyboard on the Lenovo IdeaPad Slim 3 15IWC11 (83RR) does not work correctly with the default i8042 settings. Using i8042.nopnp=1 and i8042.dumbkbd=1 restores keyboard input, but prevents the Caps Lock LED from working. Using i8042.nopnp=1 alone does not fix the keyboard. The laptop works correctly when atkbd_deactivate_fixup is used instead. Add a DMI quirk for the 83RR to enable it. This was tested without any i8042 command-line parameters. Keyboard input and the Caps Lock LED work correctly, including after suspend and resume and after a cold boot.

System suspend powers the controller off and resume powers it back on, but the resume path enables the interrupt before s6sy761_power_on() checks the boot. The firmware raises its boot-complete event on the interrupt line, the threaded handler consumes it, s6sy761_power_on() then reads an empty event and resume fails with -ENODEV, skipping the touch function setup: s6sy761 2-0048: PM: dpm_run_callback(): s6sy761_resume [s6sy761] returns -19 Power the chip on first and only then unmask the interrupt. Once resume completes the boot handshake the chip comes back with sensing off, as at probe where input_open() turns it on, so the touchscreen stays dead after resume. Send SENSE_ON again when the input device is open. Tested on a Pixel 3 XL over several s2idle cycles: resume succeeds and the touch function and sense status match the pre-suspend state.

The ThinkPad L440 also uses board id 2722, but does not have the SMBus initialization problem seen on the T440p. On the L440, the SMBus companion becomes available shortly after psmouse probes, allowing the touchpad to use SMBus/RMI4 normally. The T440p's quirk is currently applied to all Synaptics touchpads with board id 2722, unnecessarily disabling SMBus InterTouch on the L440, as reported by Daniel Salmun. Restrict the quirk to PNP ID LEN0036, which identifies the T440p, so that other devices sharing board id 2722 retain their normal SMBus/RMI4 operation.

2026-09-20Input: i8042 - add nomux quirk for Fujitsu LIFEBOOK U7410Lovekesh Solanki
On the Fujitsu LIFEBOOK U7410 the internal keyboard and touchpad die shortly after boot if i8042 multiplexing controller is probed and switched to muxed mode. These multiplexing setup commands disturb the EC emulated keyboard and atkbd reports "Spurious ACK" and "Unknown key pressed" warnings, after which both keyboard and touchpad stop delivering events. Both touchpad and keyboard work in BIOS and GRUB. Disabling multiplexer using i8042.nomux=1 makes both devices work on warm/cold boot. Add a DMI quirk to force nomux mode for this model.

2026-09-20Input: gscps2 - drop busy-wait and manual interrupt pump on transmitDmitry Torokhov
In gscps2_writeb_output(), after writing data to GSC_XMTDATA, the driver explicitly executed mdelay(6) and manually called gscps2_interrupt() as a polling mechanism to accelerate command responses (such as keyboard ACK or LED updates). On PA-RISC, the PS/2 controller asserts a level interrupt to the system ASIC whenever received data arrives in hardware, and the input/serio subsystem handles command responses asynchronously via completions. Busy-waiting for 6 ms on every transmitted byte introduces significant unnecessary latency during multi-byte command sequences and complicates interrupt handler locking. Remove mdelay(6) and the manual invocation of gscps2_interrupt() from gscps2_writeb_output(), relying on normal hardware interrupt delivery.

2026-09-20Input: gscps2 - serialize concurrent interrupt handlersDmitry Torokhov
gscps2_interrupt() may be invoked concurrently from a hardware interrupt on one CPU and from process context via gscps2_writeb_output() on another CPU. In gscps2_report_data(), ps2port->lock is released before calling serio_interrupt() to avoid recursive deadlocks. However, if two execution contexts run gscps2_report_data() concurrently for the same port, they could race to acquire serio->lock inside serio_interrupt(), potentially delivering multi-byte scancodes out of order. Serialize execution of gscps2_interrupt() using gscps2_interrupt_lock with ACQUIRE(spinlock_irqsave_try). Using spin_trylock prevents overlapping executions and guarantees in-order packet delivery without risking recursive deadlocks if an input driver synchronously sends a command back via serio_write(). If the lock cannot be acquired, return IRQ_NONE to preserve spurious interrupt detection on shared IRQ lines.

gscps2_interrupt() is registered with IRQF_SHARED. Unconditionally returning IRQ_HANDLED when no data was pending on any GSC PS/2 port masks unhandled interrupts on the shared interrupt line and prevents the kernel core spurious interrupt detector from identifying runaway interrupt storms. Have gscps2_read_data() return whether any bytes were read, accumulate the handled status in gscps2_interrupt(), and return IRQ_RETVAL(handled).

gscps2_flush() reads from hardware registers and resets the ring buffer indices ps2port->act and ps2port->append. In gscps2_enable(), the trailing gscps2_flush() was called without holding ps2port->lock, racing with concurrent hardware interrupts and buffer access. Assert that ps2port->lock is held in gscps2_flush() with lockdep_assert_held(), and ensure all callers acquire ps2port->lock so that multi-step hardware sequences remain fully serialized without unprotected windows.

2026-09-20Input: gscps2 - protect buffer access in read and report helpersDmitry Torokhov
In gscps2_report_data(), the ring buffer consumer index ps2port->act was read and updated locklessly. When gscps2_interrupt() was called from process context (such as during port write or open) concurrently with a hardware interrupt running on another CPU, two execution contexts could execute gscps2_report_data() simultaneously for the same port, racing on ps2port->act and leading to duplicate, skipped, or out-of-order bytes. Protect buffer access by taking ps2port->lock inside gscps2_read_data() and gscps2_report_data(). In gscps2_report_data(), acquire ps2port->lock only when popping entries from the ring buffer and release it before calling serio_interrupt() to avoid recursive deadlocks if the input driver synchronously sends a command back via serio_write().

2026-09-20Input: gscps2 - use RCU for ps2port_list and manage it in open/closeDmitry Torokhov
Managing ps2port_list in gscps2_probe() and gscps2_remove() had two issues: - in gscps2_remove(), serio_unregister_port() frees the serio port, but because the port remained in ps2port_list until later in remove, a shared interrupt firing on another CPU could traverse ps2port_list and dereference the freed serio port - ps2port_list additions and deletions in probe/remove raced locklessly against list traversals in gscps2_interrupt(). Convert ps2port_list traversal in gscps2_interrupt() to use RCU, and move list management to gscps2_open() and gscps2_close(). When serio_unregister_port() runs during device removal, serio_close() is invoked, cleanly taking the port out of ps2port_list before the serio structure is destroyed, while maintaining active hardware communication during child driver disconnect.

2026-09-13Input: hp_sdc - shut down kicker timer on module exitRunyu Xiao
hp_sdc_kicker() rearms hp_sdc.kicker with mod_timer() after scheduling the tasklet. The module exit path uses timer_delete_sync(). That waits for a callback already running but can still leave the timer rearmed. A callback can therefore leave the timer pending while hp_sdc_exit() tears down the driver, allowing timer activity to access dismantled driver state. Use timer_shutdown_sync() for final teardown. It waits for a running callback and prevents rearming after module exit begins.

2026-09-13Input: soc_button_array - fix MS Surface Pro 11 probe failureHans de Goede
On the MS Surface Pro 11 soc_button_array probing races with the GPIO driver probing. If soc_button_array wins the race then gpiod_get() returns EPROBE_DEFER, which should normally take care of retrying later, but the soc_button_array code deliberately ignores EPROBE_DEFER causing it to fail its probe() which causes the volume and power buttons to now work. The ignoring of EPROBE_DEFER is there to deal with a problem specific to older Bay Trail (BYT) and Cherry Trail (CHT) tablets which often use this driver. Modify the error handling to only ignore EPROBE_DEFER on BYT and CHT platforms and propagate EPROBE_DEFER normally on other platforms.

On the Acer Aspire Go 15 (AG15-42P), the internal keyboard drops out ~5 seconds after boot on both Linux and Linux-LTS kernels. Keystrokes on the built-in keyboard stop registering while the trackpad and external keyboards remain functional. Testing confirms that booting with the i8042.reset kernel parameter resolves the issue and keeps the internal keyboard responsive. Add SERIO_QUIRK_RESET_ALWAYS to i8042_dmi_quirk_table for the Acer Aspire AG15-42P to automatically apply this quirk on boot.

2026-09-13Input: synaptics - disable InterTouch on ThinkPad T440p (board id 2722)Raphaël Larocque
The Lenovo ThinkPad T440p (PNP ID LEN0036, board id 2722) has a Synaptics touchpad whose SMBus companion is not ready at boot and takes roughly 200 seconds to appear. During this window the touchpad and TrackPoint are completely unresponsive on approximately 50% of boots, making the machine unusable until the companion finally registers. The device is in the topbuttonpad_pnp_ids[] SMBus allowlist, so the kernel attempts to use SMBus/RMI4 mode by default. When the companion is not ready, psmouse_smbus_init() leaves breadcrumbs and returns -EAGAIN, the PS/2 fallback path is taken, but the device does not function properly until the companion appears and RMI4 takes over. Disable SMBus InterTouch for board id 2722 so the touchpad and TrackPoint work immediately via PS/2 from boot. Users can still force SMBus with psmouse.synaptics_intertouch=1 if needed.

2026-09-04treewide: refresh kmalloc_obj() conversionsKees Cook
This is another run of the Coccinelle script for converting kmalloc() family of allocations to kmalloc_obj() via the existing rules in scripts/coccinelle/api/kmalloc_objs.cocci This catches both the set of kmalloc() uses added since the first kmalloc_obj() conversions in v7.0 and adds a large group missed in the first pass due to Coccinelle not interacting well with the cleanup.h scoped_...() family of macros[1]. I worked around this with spatch's "--macro-file" argument to a file with all the scoped_...() macros mapped to Coccinelle's YACFE_ITERATOR[2] as that was the closest viable control flow indicator I could find. Build tested allmodconfig on x86, arm64, arm, loongarch, mips, powerpc, riscv, and s390 with no new warnings.

2026-09-01Input: zero ff_effect before compat copy in input_ff_effect_from_userIván Ezequiel Rodriguez
In the compat path input_ff_effect_from_user() aliases the caller's native struct ff_effect with the smaller struct ff_effect_compat and copies only the compat sized prefix: compat_effect = (struct ff_effect_compat *)effect; if (copy_from_user(compat_effect, buffer, sizeof(struct ff_effect_compat))) The tail of the native structure is never written. Callers pass an uninitialized on-stack object, for example evdev_do_ioctl() for EVIOCSFF, so those bytes keep their previous stack contents. input_ff_upload() then stores the full native structure in ff->effects[id], from where a uinput based force feedback daemon can read it back via UI_BEGIN_FF_UPLOAD, disclosing kernel stack memory to userspace. Zero the effect before the compat copy.

2026-09-01Input: evdev - zero absinfo before partial copy in EVIOCSABSIván Ezequiel Rodriguez
The EVIOCSABS handler copies at most the user supplied ioctl size into an uninitialized on-stack struct input_absinfo: if (copy_from_user(&abs, p, min_t(size_t, size, sizeof(struct input_absinfo)))) The size comes from _IOC_SIZE() of the ioctl command and is therefore fully controlled by userspace. A short size leaves the trailing part of the structure holding whatever was on the kernel stack, and the whole structure is then stored into the device: dev->absinfo[t] = abs; EVIOCGABS hands that back to userspace, disclosing the stale stack bytes. Only the resolution field is currently cleared, which covers the legacy struct layout but not an arbitrarily short size. Zero the structure before the copy so any part not supplied by the caller reads back as zero. The existing resolution fixup is kept, since it also handles a size that partially overlaps that field.

2026-08-30Input: synaptics-rmi4 - fix GPF in suspend and resume when unboundDmitry Torokhov
Transport drivers (such as rmi_i2c and rmi_spi) invoke rmi_driver_suspend() and rmi_driver_resume() on their child rmi_dev device during system power management events. However, transport drivers are fully registered and operational even if the physical RMI driver failed to bind or probe the rmi_dev device. When rmi_driver_suspend() or rmi_driver_resume() is called on an unbound rmi_dev, dev_get_drvdata() returns NULL. Calling rmi_disable_irq() or rmi_enable_irq() without driver data attached causes a NULL pointer dereference and General Protection Fault when attempting to lock data->enabled_mutex. Fix this by checking if driver data is attached to rmi_dev in rmi_driver_suspend() and rmi_driver_resume(), exiting early if no driver data is present.

When chunking writes into SMBus blocks in rmi_smb_write_block(), the loop calculates block_len using the original total length (len) instead of the remaining length (cur_len). If len is greater than 32 bytes (SMB_MAX_COUNT), block_len remains 32 for every iteration, even on the final partial chunk where fewer than 32 bytes remain. This causes smb_block_write() to read 32 bytes from the advanced data buffer pointer, reading past the end of the input buffer. Fix this by calculating block_len using cur_len and advancing the buffer and address pointers by block_len.

2026-08-28Input: atkbd - skip deactivate for Xiaomi Redmi Book Pro 16 2026Alexei Turtanov
The internal keyboard of the Xiaomi Redmi Book Pro 16 2026 (board TM2425) does not work: atkbd_probe() succeeds and every command is ACKed, but no scancodes ever arrive afterwards. Testing on the hardware through serio_raw shows that ATKBD_CMD_RESET_DIS (0xF5) is the culprit. After 0xF5 the embedded controller keeps ACKing commands but stops delivering scancodes, and neither ATKBD_CMD_ENABLE (0xF4) nor ATKBD_CMD_RESET_BAT (0xFF) bring them back. Only re-enabling the keyboard interface at the controller level (i8042 command 0xAE, or rewriting the command byte as i8042_port_close() does) revives it. Running the init sequence without 0xF5 (0xED 0x00, 0xF3 0x00, 0xF4) keeps the keyboard working. 'i8042.dumbkbd=1' also works around this, but then the driver never writes to the keyboard and the LEDs cannot be controlled. Use the existing atkbd_deactivate_fixup quirk instead, as done for the sibling TM2424 by commit 3a046db33bb9 ("Input: atkbd - skip deactivate for Xiaomi Book Pro 14's internal keyboard"). Tested on v7.2: keyboard, Caps Lock LED and s2idle suspend/resume all work.

2026-08-26Input: adp5588-keys - cache GPIO state before registering the gpiochipAlvin Šipraga
So as not to clobber any pre-programmed GPIO state in the execution of its gpiochip ops, the driver caches things during probe time. However, since those ops can be called both during and immediately after the call to devm_gpiochip_add_data(), it is imperative that things are cached before that. That's not the case right now, so reorder the two steps to prevent any clobbering. In the concrete example which motivated this change, a bootloader was preconfiguring an important GPIO output to HIGH before booting the kernel. Linux would then inadvertently set that output to LOW while configuring a GPIO hog on a discrete GPIO line within the same 8-bit bank (because the cached value was 0=LOW).

Often part of a more significant series. - Remove abstractions designed to allow a driver to support multiple device types, when they have been around a long time and only the original part showed up. - Initialize spi_device_id arrays using member names following dropping of driver data from drivers that didn't actually use it. - Catch up with i2c_device_id tables added since previous effort to use named initializers for all those. - Use kernel types in a few places instead of standard C ones or bare unsigned. Misc - Update Xilinx AMS maintainer. - Update email address for Maxwell Doose. - Update email address for Siratul Islam. - Update email address for Tomasz Duszynski and re-add Tomasz to various maintainer entries. Docs - Encourage use of differential channel naming even when there is no flexibility in input to differential pair mapping. Intended to provide a strong signal to userspace that a channel is differential. adi,ad_sigma_delta - Allow COMPILE_TEST without any users. adi,ad2s1201 - Refactor trigger handler to avoid mix of guard() and goto. adi,ad5686 - Avoid potential NULL dereference is user forces a driver bind. adi,ad5696 - Add a couple of missing entries to the of_match_id table and update binding to match. atmel,ad91_adc - Use const char * for DT string property allowing a cast to be dropped. avia,hx711 - Various refactors and cleanup to enable support of additional parts (to come) - Add missing supply and gpio dt-bindings. bosch,bmc150 - Harden against device reporting too large a FIFO sample count. - Use FIELD_PREP() / FIELD_GET() to improve readability. freescale,fxls8962af - Harden against device reporting too large a FIFO sample count. hid-sensors-* - Reorder probe to not expose userspace interfaces until the rest of the setup is done to avoid potentially dropping data. honeywell,abp2030pa - Drop an unreachable return. invensens,icm45600 - Harden against bad value of FIFO sample count from device. - Use i2c_match_data if firmware table sourced match data isn't available. nxp,mpl1115 - Ensure runtime_pm is balanced on error in probe. rohm,bm1390 - Make the driver slightly more likely to recover from transient errors. sensiron,sgp30 - Handle thread creation errors. st,lsm6dsx - Update the enable mask when doing sensor fusion to avoid incorrect fifo data handling. st,stm32-dfsdm - Treat dt flags as booleans. ti,ads1015 - Switch to devm helpers which simplified code and closed a resource leak. ti,opt3001 - Split complicated opt3001_get_processed() logic into irq an no irq helper functions. - Use devm to simplify code. - Use guard() to simplify code. - Reorder probe so final call exposes userspace interfaces. - Various other more minor cleanup taos,tsl2772 - Fix calibscale readback to check right channel type. taos,tsl2583 - Use sysfs_emit() and sysfs_emit_at() to replace open coded equivalents. * tag 'iio-for-7.3a' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/jic23/iio: (232 commits) iio: dac: mcp47a1: add support for new device dt-bindings: iio: dac: add support for mcp47a1 iio: Update email for Maxwell Doose iio: imu: st_lsm6dsx: Update enable mask when using sensor fusion iio: light: cm32181: return zero after writing calibscale iio: flow: add Sensirion SLF3S liquid flow sensor driver iio: core: add IIO_VAL_DECIMAL64_FEMTO format type dt-bindings: iio: flow: add Sensirion SLF3S liquid flow sensor iio: types: add IIO_VOLUMEFLOW channel type iio: ABI: Encourage differential voltage ABI usage iio: adc: ltc2378: Add support for LTC2338-18 iio: adc: ltc2378: Enable triggered buffer data capture iio: adc: ltc2378: Enable high-speed data capture iio: adc: ltc2378: Add support for LTC2378-20 and similar ADCs dt-bindings: iio: adc: Add ltc2378 iio: magnetometer: ak8974: remove conditional return with no effect iio: light: tsl2583: remove conditional return with no effect iio: adc: rcar-gyroadc: remove rcar_gyroadc_set_power() helper iio: light: vcnl4000: remove vcnl4000_set_pm_runtime_state() helper iio: light: vcnl4035: remove vcnl4035_set_pm_runtime_state() helper ...
