5ea6b1702781 ("drm/panel: Add prepare_prev_first flag to

However, due to the unusual ERR_PTR check when getting that pointer, the

Rework the function for a more traditional design that will return
immediately if it gets an ERR_PTR so that we never access the pointer in
that case.

- Also convert alpha formats to their non-alpha counterparts. Generic

drm/tiny: ili9486: Do not assume 8-bit only SPI controllers
The pixel data for the ILI9486 is always 16-bits wide and it must be
sent over the SPI bus. When the controller is only able to deal with
8-bit transfers, this 16-bits data needs to be swapped before the
sending to account for the big endian bus, this is on the contrary not
needed when the SPI controller already supports 16-bits transfers.
The decision about swapping the pixel data or not is taken in the MIPI
DBI code by probing the controller capabilities: if the controller only
suppors 8-bit transfers the data is swapped, otherwise it is not.
This swapping/non-swapping is relying on the assumption that when the
controller does support 16-bit transactions then the data is sent
unswapped in 16-bits-per-word over SPI.
The problem with the ILI9486 driver is that it is forcing 8-bit
transactions also for controllers supporting 16-bits, violating the
assumption and corrupting the pixel data.
Align the driver to what is done in the MIPI DBI code by adjusting the
transfer size to the maximum allowed by the SPI controller.

drm/display/dp_mst: Fix payload addition on a disconnected sink
If an MST stream is enabled on a disconnected sink, the payload for the
stream is not created and the MST manager's payload count/next start VC
slot is not updated. Since the payload's start VC slot may still contain
a valid value (!= -1) the subsequent disabling of such a stream could
cause an incorrect decrease of the payload count/next start VC slot in

Fix the above by marking the payload as invalid in the above case, so

drm: exynos: Remove #ifdef guards for PM related functions
Use the DEFINE_RUNTIME_DEV_PM_OPS(), SYSTEM_SLEEP_PM_OPS(),
RUNTIME_PM_OPS() and pm_ptr() macros to handle the runtime and suspend
PM callbacks.
These macros allow the suspend and resume functions to be automatically
dropped by the compiler when CONFIG_PM is disabled, without having
to use #ifdef guards.
This has the advantage of always compiling these functions in,
independently of any Kconfig option. Thanks to that, bugs and other
regressions are subsequently easier to catch.

drm/i915/gt: Remove #ifdef guards for PM related functions
Instead of defining two versions of intel_sysfs_rc6_init(), one for each
value of CONFIG_PM, add a check on !IS_ENABLED(CONFIG_PM) early in the
function. This will allow the compiler to automatically drop the dead
code when CONFIG_PM is disabled, without having to use #ifdef guards.
