- Add a missing refcount decrement in ata_scsi_dev_rescan() when
the device or its queue is not running.
In the case where the device is running, the recount is already
decremented properly (Yihang Li)
- Generate the proper sense code for a Security locked device.
There was a regression caused by a recent change of how sense
data is generated for commands that did not provide any sense
data. This broke system suspend for Security locked devices.
Generate the sense data that the SCSI disk driver expects for a
Security locked device so that system suspend works again (me)
- Set capacity to zero for a Security locked device.
All I/O commands will be aborted by a Security locked device.
Thus, the block layer disk partition scanning will result in
a bunch of, for the user, confusing I/O errors in dmesg during
boot.
Since a Security locked device is unusable anyway, set the capacity
to zero, to avoid the disk partition scanning during boot. We still
create the block device in /dev such that the user may unlock the
device using e.g. hdparm (me)

Commit cf3fc037623c ("ata: libata-scsi: Fix ata_to_sense_error() status
handling") fixed ata_to_sense_error() to properly generate sense key
ABORTED COMMAND (without any additional sense code), instead of the
previous bogus sense key ILLEGAL REQUEST with the additional sense code
UNALIGNED WRITE COMMAND, for a failed command.
However, this broke suspend for Security locked drives (drives that have
Security enabled, and have not been Security unlocked by boot firmware).
The reason for this is that the SCSI disk driver, for the Synchronize
Cache command only, treats any sense data with sense key ILLEGAL REQUEST
as a successful command (regardless of ASC / ASCQ).
After commit cf3fc037623c ("ata: libata-scsi: Fix ata_to_sense_error()
status handling") the code that treats any sense data with sense key
ILLEGAL REQUEST as a successful command is no longer applicable, so the
command fails, which causes the system suspend to be aborted:
sd 1:0:0:0: PM: dpm_run_callback(): scsi_bus_suspend returns -5
sd 1:0:0:0: PM: failed to suspend async: error -5
PM: Some devices failed to suspend, or early wake event detected
To make suspend work once again, for a Security locked device only,
return sense data LOGICAL UNIT ACCESS NOT AUTHORIZED, the actual sense
data which a real SCSI device would have returned if locked.
The SCSI disk driver treats this sense data as a successful command.

Correct RGMII delay application logic in lan937x_set_tune_adj().
The function was missing `data16 &= ~PORT_TUNE_ADJ` before setting the
new delay value. This caused the new value to be bitwise-OR'd with the
existing PORT_TUNE_ADJ field instead of replacing it.
For example, when setting the RGMII 2 TX delay on port 4, the
intended TUNE_ADJUST value of 0 (RGMII_2_TX_DELAY_2NS) was
incorrectly OR'd with the default 0x1B (from register value 0xDA3),
leaving the delay at the wrong setting.
This patch adds the missing mask to clear the field, ensuring the
correct delay value is written. Physical measurements on the RGMII TX
lines confirm the fix, showing the delay changing from ~1ns (before
change) to ~2ns.
While testing on i.MX 8MP showed this was within the platform's timing
tolerance, it did not match the intended hardware-characterized value.

sg_finish_rem_req() calls blk_rq_unmap_user(). The latter function may
sleep. Hence, call sg_finish_rem_req() with interrupts enabled instead
of disabled.

Scanning can be offloaded to the firmware. To that end, the driver
prepares a list of channels to scan, including periodic visits back to
the operating channel, and sends the list to the firmware.
When the channel list is too long to fit in a single H2C message, the
driver splits the list, sends the first part, and tells the firmware to
scan. When the scan is complete, the driver sends the next part of the
list and tells the firmware to scan.
When the last channel that fit in the H2C message is the operating
channel something seems to go wrong in the firmware. It will
acknowledge receiving the list of channels but apparently it will not
do anything more. The AP can't be pinged anymore. The driver still
receives beacons, though.
One way to avoid this is to split the list of channels before the
operating channel.
Affected devices:
* RTL8851BU with firmware 0.29.41.3
* RTL8832BU with firmware 0.29.29.8
* RTL8852BE with firmware 0.29.29.8
The commit 57a5fbe39a18 ("wifi: rtw89: refactor flow that hw scan handles channel list")
is found by git blame, but it is actually to refine the scan flow, but not
a culprit, so skip Fixes tag.

The MMIO_REMAP BO is a special 4K IO page that does not have a ttm_tt
behind it. However, amdgpu_ttm_tt_pde_flags() was treating it like
normal TT/doorbell/preempt memory and unconditionally accessed
ttm->caching. For the MMIO_REMAP BO, ttm is NULL, so this leads to a
NULL pointer dereference when computing PDE flags.
Fix this by checking that ttm is non-NULL before reading ttm->caching.
This prevents the crash for MMIO_REMAP and also makes the code more
defensive if other BOs ever come through without a ttm_tt.

[Why]
Accoreding to CP updated to RS64 on gfx11,
WRITE_DATA with PREEMPTION_META_MEMORY(dst_sel=8) is illegal for CP FW.
That packet is used for MCBP on F32 based system.
So it would lead to incorrect GRBM write and FW is not handling that
extra case correctly.
[How]
With gfx11 rs64 enabled, skip emit de meta data.

During the suspend sequence VPE is already going to be power gated
as part of vpe_suspend(). It's unnecessary to call during calls to
amdgpu_device_set_pg_state().
It actually can expose a race condition with the firmware if s0i3
sequence starts as well. Drop these calls.

Pause, Asym_Pause and Autoneg bits are not set when pl->supported is
initialized, so these link modes will not work for the fixed-link. This
leads to a TCP performance degradation issue observed on the i.MX943
platform.
The switch CPU port of i.MX943 is connected to an ENETC MAC, this link
is a fixed link and the link speed is 2.5Gbps. And one of the switch
user ports is the RGMII interface, and its link speed is 1Gbps. If the
flow-control of the fixed link is not enabled, we can easily observe
the iperf performance of TCP packets is very low. Because the inbound
rate on the CPU port is greater than the outbound rate on the user port,
the switch is prone to congestion, leading to the loss of some TCP
packets and requiring multiple retransmissions.
Solving this problem should be as simple as setting the Asym_Pause and
Pause bits. The reason why the Autoneg bit needs to be set, Russell
has gave a very good explanation in the thread [1], see below.
"As the advertising and lp_advertising bitmasks have to be non-empty,
and the swphy reports aneg capable, aneg complete, and AN enabled, then
for consistency with that state, Autoneg should be set. This is how it
was prior to the blamed commit."

ACPI 6.6 specification for EINJV2 appends an extra structure to
the end of the existing struct set_error_type_with_address.
Several issues showed up in testing.
1) Initialization was broken by an earlier fix [1] since is_v2 is only
set while performing an injection, not during initialization.
2) A buggy BIOS provided invalid "revision" and "length" for the
extension structure. Add several sanity checks.
3) When injecting legacy error types on an EINJV2 capable system,
don't copy the component arrays.

With the final call to fput() on a file descriptor, the release action
may be deferred and scheduled on a work queue. The reference count of
that descriptor is still zero and it must not be used. It's possible
that a GPIO change, we want to notify the user-space about, happens
AFTER the reference count on the file descriptor associated with the
character device went down to zero but BEFORE the .release() callback
was called from the workqueue and so BEFORE we unregistered from the
notifier.
Using the regular get_file() routine in this situation triggers the
following warning:
struct file::f_count incremented from zero; use-after-free condition present!
So use the get_file_active() variant that will return NULL on file
descriptors that have been or are being released.

The mlx5_irq_alloc() function can inadvertently free the entire rmap
and end up in a crash[1] when the other threads tries to access this,
when request_irq() fails due to exhausted IRQ vectors. This commit
modifies the cleanup to remove only the specific IRQ mapping that was
just added.
This prevents removal of other valid mappings and ensures precise
cleanup of the failed IRQ allocation's associated glue object.
Note: This error is observed when both fwctl and rds configs are enabled.

s32_pmx_gpio_request_enable() does not initialize the newly-allocated
gpio_pin_config::list before adding it to s32_pinctrl::gpio_configs.
This could result in a linked list corruption.
Initialize the new list_head with INIT_LIST_HEAD() to fix this.

s32_pinctrl_desc is allocated with devm_kmalloc(), but not all of its
fields are initialized. Notably, num_custom_params is used in
pinconf_generic_parse_dt_config(), resulting in intermittent allocation
errors, such as the following splat when probing i2c-imx:

Fix this by initializing s32_pinctrl_desc with devm_kzalloc() instead of
devm_kmalloc() in s32_pinctrl_probe(), which sets the previously
uninitialized fields to zero.

Improve the cleanup on releasing PTP resources in error path.
The error case might happen either at the driver probe and PTP
feature initialization or on PTP restart (errors in reset handling, NVM
update etc). In both cases, calls to PF PTP cleanup (ice_ptp_cleanup_pf
function) and 'ps_lock' mutex deinitialization were missed.
Additionally, ptp clock was not unregistered in the latter case.
Keep PTP state as 'uninitialized' on init to distinguish between error
scenarios and to avoid resource release duplication at driver removal.
The consequence of missing ice_ptp_cleanup_pf call is the following call
trace dumped when ice_adapter object is freed (port list is not empty,
as it is required at this stage):

Current gu2host handler registered as MSI-X vector 0 and as per bspec for
a msix vector 0 interrupt, the driver must check the legacy registers
190008(TILE_INT_REG), 190060h (GT INTR Identity Reg 0) and other registers
mentioned in "Interrupt Service Routine Pseudocode" otherwise it will block
the next interrupts. To overcome this issue replacing guc2host handler
with legacy xe_irq_handler.
