Use common helper for checking the contiguity of the imported dma-buf and
do this check before allocating resources, so the error path is simpler.

For current mediatek dsi encoder, its possible crtc is fixed in crtc
0, and mediatek dpi encoder's possible crtc is fixed in crtc 1. In
some SoC the possible crtc is not fixed in this case, so search
pipeline information to find out the correct possible crtc.

Pull ARM SoC driver updates from Arnd Bergmann:
"A couple of subsystems have their own subsystem maintainers but choose
to have the code merged through the soc tree as upstream, as the code
tends to be used across multiple SoCs or has SoC specific drivers
itself:
- memory controllers:
Krzysztof Kozlowski takes ownership of the drivers/memory subsystem
and its drivers, starting out with a set of cleanup patches.
A larger driver for the Tegra memory controller that was
accidentally missed for v5.8 is now added.
- reset controllers:
Only minor updates to drivers/reset this time
- firmware:
The "turris mox" firmware driver gains support for signed firmware
blobs The tegra firmware driver gets extended to export some debug
information Various updates to i.MX firmware drivers, mostly
cosmetic
- ARM SCMI/SCPI:
A new mechanism for platform notifications is added, among a number
of minor changes.
- optee:
Probing of the TEE bus is rewritten to better support detection of
devices that depend on the tee-supplicant user space. A new
firmware based trusted platform module (fTPM) driver is added based
on OP-TEE
- SoC attributes:
A new driver is added to provide a generic soc_device for
identifying a machine through the SMCCC ARCH_SOC_ID firmware
interface rather than by probing SoC family specific registers.
The series also contains some cleanups to the common soc_device
code.
There are also a number of updates to SoC specific drivers, the main
ones are:
- Mediatek cmdq driver gains a few in-kernel interfaces
- Minor updates to Qualcomm RPMh, socinfo, rpm drivers, mostly adding
support for additional SoC variants
- The Qualcomm GENI core code gains interconnect path voting and
performance level support, and integrating this into a number of
device drivers.
- A new driver for Samsung Exynos5800 voltage coupler for
- Renesas RZ/G2H (R8A774E1) SoC support gets added to a couple of SoC
specific device drivers
- Updates to the TI K3 Ring Accelerator driver"

Hisilicon hi6220
- The SCMI firmware interface can now work across ARM SMC/HVC as a
transport.
- Mediatek platforms now use a new driver for their "MMSYS" hardware
block that controls clocks and some other aspects in behalf of the
media and gpu drivers.
- Some Tegra processors have improved power management support,
including getting woken up by the PMIC and cluster power down
during idle.
- A new v4l staging driver for Tegra is added.
- Cleanups and minor bugfixes for TI, NXP, Hisilicon, Mediatek, and
Tegra"

Get rid of mode->vrefresh and just calculate it on demand. Saves
a bit of space and avoids the cached value getting out of sync
with reality.
Mostly done with cocci, with the following manual fixups:
- Remove the now empty loop in drm_helper_probe_single_connector_modes()
- Fix __MODE() macro in ch7006_mode.c
- Fix DRM_MODE_ARG() macro in drm_modes.h
- Remove leftover comment from samsung_s6d16d0_mode
- Drop the TODO

Spelling out _unlocked for each and every driver is a annoying.
Especially if we consider how many drivers, do not know (or need to)
about the horror stories involving struct_mutex.
Just drop the suffix. It makes the API cleaner.
Done via the following script:
__from=drm_gem_object_put_unlocked
__to=drm_gem_object_put
for __file in $(git grep --name-only $__from); do
sed -i "s/$__from/$__to/g" $__file;

In the actual implementation the same compatible string
"mediatek,<chip>-mmsys" is used to bind the clock drivers
(drivers/soc/mediatek) as well as to the gpu driver
(drivers/gpu/drm/mediatek/mtk_drm_drv.c). This ends with the problem
that the only probed driver is the clock driver and there is no display
at all.
In any case having the same compatible string for two drivers is not
correct and should be fixed. To fix this, and maintain backward
compatibility, we can consider that the mmsys driver is the top-level
entry point for the multimedia subsystem, so is not a pure clock
controller but a system controller, and the drm driver is instantiated
by that MMSYS driver.

Pull sound updates from Takashi Iwai:
"This became again a busy development cycle. There are few ALSA core
updates (merely API cleanups and sparse fixes), with the majority of
other changes are found in ASoC scene.
Here are some highlights:
ALSA core:
- More helper macros for sparse warning fixes (e.g. bitwise types)
- Slight optimization of PCM OSS locks
- Make common handling for PCM / compress buffers (for SOF)
ASoC:
- Lots of code refactoring and modernization for (still ongoing)
componentization works
- Conversion of SND_SOC_ALL_CODECS to use imply
- Continued refactoring and fixing of the Intel SOF/SST support,
including the initial (but still incomplete) SoundWire support
- SoundWire and more advanced clocking support for Realtek RT5682
- Support for amlogic GX, Meson 8, Meson 8B and T9015 DAC, Broadcom
DSL/PON, Ingenic JZ4760 and JZ4770, Realtek RL6231, and TI TAS2563
and TLV320ADCX140

- Optimizations in HDMI jack handling
- A few new quirks and fixups for Realtek codecs
USB-audio:
- Delayed registration support
- New quirks for Motu, Kingston, Presonus"

It's right above the drm_dev_put().
This is made possible by a preceeding patch which added a drmm_
cleanup action to drm_mode_config_init(), hence all we need to do to
ensure that drm_mode_config_cleanup() is run on final drm_device
cleanup is check the new error code for _init().
Aside: Another driver with a bit much devm_kzalloc, which should
probably use drmm_kzalloc instead ...
v2: Explain why this cleanup is possible (Laurent).
v3: Use drmm_mode_config_init() for more clarity (Sam, Thomas)
