SPI driver_override allows a device to bind to this driver without
matching either the OF or SPI device ID table. In that case,
spi_get_device_match_data() returns NULL.
sca3000_probe() immediately dereferences the returned chip information
to set the IIO device name and channel layout, causing a NULL pointer
dereference.
Commit 572a00852635 ("iio: dac: ad5686: missing NULL check on match
data") fixed the same driver_override issue in another SPI driver.
Reject devices without match data before using the chip information.

The IIO core does not filter duplicate writes to the event enable
attribute. kxcjk1013_write_event_config() already ignores repeated
enable requests, but a repeated disable request still calls
kxcjk1013_set_power_state(data, false), dropping a runtime PM reference
that was not acquired for this request. This can underflow the runtime
PM usage count and trigger a "Runtime PM usage count underflow" warning.
Return early when the requested state already matches ev_enable_state.

The SPI driver advertises an ACPI match for BMA0220 but does not export
that table. A modular build therefore lacks the ACPI alias used to load
the driver when the device is enumerated through ACPI.
Export the ACPI table. Move the existing SPI export next to its SPI ID
table so each export is adjacent to the table it describes.
The issue was found by our static-analysis tool.

The ADXL367 provides two independent interrupt output pins, INT1 and
INT2, each with its own event mapping register (INTMAP1_LOWER at 0x2A
and INTMAP2_LOWER at 0x2B) sharing an identical bit layout. Until now
the driver hardcoded INT1 for all interrupt mappings, so a board that
routes only INT2 to the host could never receive activity, inactivity
or FIFO watermark interrupts.
Determine the connected pin from the interrupt-names device tree
property using fwnode_irq_get_byname(), and route the interrupt
mappings to the matching register. Use the interrupt number returned by
the lookup for devm_request_threaded_irq() so the requested line always
matches the routed INTMAP register, regardless of the order in which the
interrupts are listed. When no interrupt-names are present, default to
INT1 and the bus-provided interrupt to preserve the existing behaviour.

When setting the sampling frequency, the check for `base_freq / 2` is
followed by an independent `if` statement for `base_freq / 4`. If `val`
equals `base_freq / 2`, the second check fails and falls through to the
`else if (val != base_freq)` branch, returning `-EINVAL` erroneously.
Fix this by chaining the checks with `else if`.

The FIFO entry count reported by the device can be as large as 1023
(the low byte plus the low two bits of the high byte), but fifo_buf[]
only has room for ADXL367_FIFO_SIZE (512) entries.
adxl367_push_fifo_data() passes the reported count straight to the FIFO
read, so a count above ADXL367_FIFO_SIZE overflows fifo_buf, a heap
out-of-bounds write of up to 1022 bytes into adjacent memory.
Rather than clamp the count and silently drop the excess, abort the
read: a count beyond the FIFO size means the device is returning
garbage, so the data cannot be trusted. The message is ratelimited
because a stuck device can raise the IRQ repeatedly.

The driver kept two separate staging areas that hold the same thing:
buffer[8], a DMA-aligned area used by the one-shot read in
kx022a_get_axis() and by the triggered handler, and the scan struct,
used by the FIFO flush path. Both are three __le16 channels plus room
for the timestamp.
Drop buffer and route the one-shot read and the triggered handler
through scan.channels, so the driver has a single staging area. Move the
IIO_DMA_MINALIGN alignment onto scan, since it now backs the regmap bulk
reads that buffer used to.
No functional change. get_axis() only runs via read_raw() under
iio_device_claim_direct(), so it cannot run while the triggered buffer is
active, and the triggered handler only runs while it is; the two never
touch scan concurrently, exactly as they previously shared buffer.

42 are missing includes of interrupt.h (the question of why swap.h
brings in interrupt.h remains unanswered).
10 missing includes of seq_file.h

some new ABI for input chopping, particular useful for resistive sensors
like thermocouples or Wheatstone bridges.
- Support CRC8 detection of corruption on the bus.
- Support buffered reads.
ti,tmp117
- (trivial) Add support for the tmp119 temperature sensor.
xilinx,versal-sysmon
- New ADC driver for this block found on various FPGAs including various
bus interfaces, threshold and oversampling support.
dt binding updates
------------------
new shared bindings
- excitation-channels and excitation-current-nanoamp allow per channel
specification of currents used for resistive sensor measurement.
- reference-sources property to allow selection of a per channel reference.
rockchip,saradc
- Add RV1106 which is compatible with the RV3588.
Features
--------
buffer-dmaengine
- Allow cyclic buffers, useful for repeating sequence generation with DACs.

Cleanups, minor fixes
---------------------
Minor cleanups not mentioned at all in this summary such
as white space fixes or typos.
Affecting various drivers
- Cleanup of conditionals that had no affect.
- Drop some runtime pm local wrappers as now runtime_pm does the
mark_last_busy part inside the put, these provide no useful code
deduplication or readability advantages over directly calling the
runtime_pm functions.
- Return 0 from write_raw() on success.
- Use of dev_err_probe() to simplify code and sometimes provide useful
info for deferred probe debugging.
- Drop some redundant error prints where the called function already
provides information on errors.
- Make some read only arrays in functions static.
- Fix up missing handling of regcache_sync() errors.
- Drop some false kernel-doc markings.
- Add missing MODULE_DEVICE_TABLE for some of_match_id tables.
- Use local variables for things like the struct device to shorten and
improve readability of code.
- Drop some unused structure elements.
- Reorder dds.h macro parameters to be inline with others.
- Header reorders and IWYU. 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

Reading the in_accel_scale attribute on the DMARD09 has always returned
-EINVAL: the channels advertise scale via info_mask_shared_by_type so the
IIO core exposes the attribute, but dmard09_read_raw() only handles
IIO_CHAN_INFO_RAW, so a SCALE read falls through to 'default: return
-EINVAL':
$ cat .../iio:deviceX/in_accel_scale
cat: in_accel_scale: Invalid argument
leaving userspace with raw counts it cannot convert to m/s^2.
The driver was written from a vendor source [1] without a datasheet, and
the scale was declared but never implemented. The vendor source carries
the sensitivity: its conversion is
acc = raw * GRAVITY_EARTH_1000 / sensitivity (then / 1000 -> m/s^2)
with sensitivity = 32 and GRAVITY_EARTH_1000 = 9807 ("about
(9.80665)*1000"), i.e. 32 counts correspond to 1 g.
That sensitivity applies to the value this driver already reports as raw:
the vendor reduces each 16-bit sample to a signed 9-bit value, and the
preparation in dmard09_read_raw() yields the same value. It is
self-consistent: 256 counts / 32 = 8 g full scale, matching the +/-8g
range.
Implement the scale derived from that sensitivity using standard gravity:
scale = 9.80665 / 32 = 0.3064578125 m/s^2 per LSB

device exposure
The driver currently exposes the IIO device to userspace before
completing sensor hub callback registration, and similarly removes
callbacks while the device can still be accessed during teardown.
This creates a timing window where userspace may enable the buffer
before callbacks are available. In such cases:
- samples can be dropped,
- buffered reads may observe stale or no data.
Reorder probe and remove paths to ensure callbacks are active before
device exposure and are removed after device is no longer accessible.
This avoids a race window leading to data loss.

While being less compact, using named initializers allows to more easily
see which members of the structs are assigned which value without having
to lookup the declaration of the struct. And it's also more robust
against changes to the struct definition.
The mentioned robustness is relevant for a planned change to struct
spi_device_id that replaces .driver_data by an anonymous union.
This patch doesn't modify the compiled arrays, only their representation
in source form benefits. The former was confirmed with x86 and arm64
builds.

spi_device_id to zero without relying on that value. Drop these unused
assignments.
While touching these arrays unify spacing and use named initializers for
.name.

There is one id entry that has an explicit assignment to .driver_data.
To make the intention clearer, assign BOSCH_UNKNOWN (which is also 0)
for all previously ids that had .driver_data = 0 implicitly before.
While touching all entries in this array, convert to named initializers.
This change is similar to commit e50856dc41e8 ("iio: accel: bmc150:
Explicitly set .driver_data") but cares for the driver's spi part
instead of i2c.

fxls8962af_fifo_flush() transfers the sample count the device reports in
BUF_STATUS into an on-stack buffer sized for FXLS8962AF_FIFO_LENGTH (32)
samples, but the count is a 6-bit field (0..63) that is only checked for
zero. A device, or an attacker on the I2C/SPI bus, reporting 33..63
overflows the buffer by up to 186 bytes: a stack out-of-bounds write.
Clamp the count to FXLS8962AF_FIFO_LENGTH before the transfer, mirroring
the clamp already applied in fxls8962af_set_watermark(). Conforming
hardware reports at most that many samples and is unaffected.

but returns -EINVAL directly when a scale with a non-zero integer part is
requested, skipping the matching pm_runtime_put_autosuspend(). This leaks
a runtime PM usage-counter reference on every such write, after which the
device can no longer autosuspend.
