The Xe driver fails to build when CONFIG_DRM_XE_GPUSVM is disabled
but CONFIG_DRM_GPUSVM is turned on, due to the clash of two commits:

The current implementation overlooks the 'guaranteed_perf'
register in this check.
If the Guaranteed Performance register is located in the PCC
subspace, the function currently attempts to read it without
acquiring the lock and without sending the CMD_READ doorbell
to the firmware. This can result in reading stale data.

Fix inconsistent error handling for sscanf() return value check.
Implicit boolean conversion is used instead of explicit return
value checks. The code checks if (!sscanf(...)) which is incorrect
because:
1. sscanf returns the number of successfully parsed items
2. On success, it returns 1 (one item passed)
3. On failure, it returns 0 or EOF
4. The check 'if (!sscanf(...))' is wrong because it treats
success (1) as failure
All occurrences of sscanf() now uses explicit return value check.
With this behavior it returns '-EINVAL' when parsing fails (returns
0 or EOF), and continues when parsing succeeds (returns 1).

The device becomes visible to userspace via device_register()
even before it fully initialized by idr_init(). If userspace
or another thread tries to register a zone immediately after
device_register(), the control_type_valid() will fail because
the control_type is not yet in the list. The IDR is not yet
initialized, so this race condition causes zone registration
failure.
Move idr_init() and list addition before device_register()
fix the race condition.

The driver computes conversion intervals using the formula:
interval = (1 << (7 - rate)) * 125ms
where 'rate' is the sensor's conversion rate register value. According to
the datasheet, the power-on reset value of this register is 0x8, which
could be assigned to the register, after handling i2c general call.
Using this default value causes a result greater than the bit width of
left operand and an undefined behaviour in the calculation above, since
shifting by values larger than the bit width is undefined behaviour as
per C language standard.
Limit the maximum usable 'rate' value to 7 to prevent undefined
behaviour in calculations.
Found by Linux Verification Center (linuxtesting.org) with Svace.
Note (groeck):
This does not matter in practice unless someone overwrites the chip
configuration from outside the driver while the driver is loaded.
The conversion time register is initialized with a value of 5 (500ms)
when the driver is loaded, and the driver never writes a bad value.

The ibmpex_high_low_store() function retrieves driver data using
dev_get_drvdata() and uses it without validation. This creates a race
condition where the sysfs callback can be invoked after the data
structure is freed, leading to use-after-free.
Fix by adding a NULL check after dev_get_drvdata(), and reordering
operations in the deletion path to prevent TOCTOU.

The fan nominal speed returned by SMM is limited to 16 bits, but the
driver allows the fan multiplier to be set via a module parameter.
Clamp the computed fan multiplier so that fan_nominal_speed *
i8k_fan_mult always fits into a signed 32-bit integer and refuse to
initialize the driver if the value is too large.

Commit fc96ec826bce ("spi: fsl-cpm: Use 16 bit mode for large transfers
with even size") failed to make sure that the size is really even
before switching to 16 bit mode. Until recently the problem went
unnoticed because kernfs uses a pre-allocated bounce buffer of size
PAGE_SIZE for reading EEPROM.
But commit 8ad6249c51d0 ("eeprom: at25: convert to spi-mem API")
introduced an additional dynamically allocated bounce buffer whose size
is exactly the size of the transfer, leading to a buffer overrun in
the fsl-cpm driver when that size is odd.
Add the missing length parity verification and remain in 8 bit mode
when the length is not even.

Initializing automatic __free variables to NULL without need (e.g.
branches with different allocations), followed by actual allocation is
in contrary to explicit coding rules guiding cleanup.h:
"Given that the "__free(...) = NULL" pattern for variables defined at
the top of the function poses this potential interdependency problem the
recommendation is to always define and assign variables in one statement
and not group variable definitions at the top of the function when
__free() is used."
Code does not have a bug, but is less readable and uses discouraged
coding practice, so fix that by moving declaration to the place of
assignment.

EDEADLK
Fedora/CentOS/RHEL CI is reporting intermittent failures while running
the KUnit tests present in drm_hdmi_state_helper_test.c [1].
While the specific test causing the failure change between runs, all of
them are caused by drm_kunit_helper_enable_crtc_connector() returning
-EDEADLK. The error trace always follow this structure:
# <test name>: ASSERTION FAILED at
# drivers/gpu/drm/tests/drm_hdmi_state_helper_test.c:<line>
Expected ret == 0, but
ret == -35 (0xffffffffffffffdd)
As documented, if the drm_kunit_helper_enable_crtc_connector() function
returns -EDEADLK (-35), the entire atomic sequence must be restarted.
Handle this error code for all function calls.

lkkbd_interrupt() schedules lk->tq via schedule_work(), and the work
handler lkkbd_reinit() dereferences the lkkbd structure and its
serio/input_dev fields.
lkkbd_disconnect() and error paths in lkkbd_connect() free the lkkbd
structure without preventing the reinit work from being queued again
until serio_close() returns. This can allow the work handler to run
after the structure has been freed, leading to a potential use-after-free.
Use disable_work_sync() instead of cancel_work_sync() to ensure the
reinit work cannot be re-queued, and call it both in lkkbd_disconnect()
and in lkkbd_connect() error paths after serio_open().

Some Potron SFP+ XGSPON ONU sticks are shipped with different EEPROM
vendor ID and vendor name strings, but are otherwise functionally
identical to the existing "Potron SFP+ XGSPON ONU Stick" handled by
sfp_quirk_potron().
These modules, including units distributed under the "Better Internet"
branding, use the same UART pin assignment and require the same
TX_FAULT/LOS behaviour and boot delay. Re-use the existing Potron
quirk for this EEPROM variant.
