Pull asm-generic fixes from Arnd Bergmann:
 "There is one build fix for Arm platforms that ended up impacting most
  architectures because of the way the drivers/firmware Kconfig file is
  wired up:

  The CONFIG_QCOM_SCM dependency have caused a number of randconfig
  regressions over time, and some still remain in v5.15-rc4. The fix we
  agreed on in the end is to make this symbol selected by any driver
  using it, and then building it even for non-Arm platforms with
  CONFIG_COMPILE_TEST.

  To make this work on all architectures, the drivers/firmware/Kconfig
  file needs to be included for all architectures to make the symbol
  itself visible.

  In a separate discussion, we found that a sound driver patch that is
  pending for v5.16 needs the same change to include this Kconfig file,
  so the easiest solution seems to have my Kconfig rework included in
  v5.15.

  Finally, the branch also includes a small unrelated build fix for
  NOMMU architectures"

qcom_scm: hide Kconfig symbol

2021-10-07T14:51:57+00:00

Now that SCM can be a loadable module, we have to add another
dependency to avoid link failures when ipa or adreno-gpu are
built-in:

aarch64-linux-ld: drivers/net/ipa/ipa_main.o: in function `ipa_probe':
ipa_main.c:(.text+0xfc4): undefined reference to `qcom_scm_is_available'

ld.lld: error: undefined symbol: qcom_scm_is_available
>>> referenced by adreno_gpu.c
>>>               gpu/drm/msm/adreno/adreno_gpu.o:(adreno_zap_shader_load) in archive drivers/built-in.a

This can happen when CONFIG_ARCH_QCOM is disabled and we don't select
QCOM_MDT_LOADER, but some other module selects QCOM_SCM. Ideally we'd
use a similar dependency here to what we have for QCOM_RPROC_COMMON,
but that causes dependency loops from other things selecting QCOM_SCM.

This appears to be an endless problem, so try something different this
time:

 - CONFIG_QCOM_SCM becomes a hidden symbol that nothing 'depends on'
   but that is simply selected by all of its users

 - All the stubs in include/linux/qcom_scm.h can go away

 - arm-smccc.h needs to provide a stub for __arm_smccc_smc() to
   allow compile-testing QCOM_SCM on all architectures.

 - To avoid a circular dependency chain involving RESET_CONTROLLER
   and PINCTRL_SUNXI, drop the 'select RESET_CONTROLLER' statement.
   According to my testing this still builds fine, and the QCOM
   platform selects this symbol already.

media: s5p-jpeg: rename JPEG marker constants to prevent build warnings

2021-09-07T05:57:59+00:00

The use of a macro named 'RST' conflicts with one of the same name
in arch/mips/include/asm/mach-rc32434/rb.h. This causes build
warnings on some MIPS builds.

Change the names of the JPEG marker constants to be in their own
namespace to fix these build warnings and to prevent other similar
problems in the future.

Fixes these build warnings:

Also update the kernel-doc so that the word "marker" is not
repeated.

media: venus: helper: do not set constrained parameters for UBWC

2021-08-04T12:43:52+00:00

Plane constraints firmware interface is to override the default
alignment for a given color format. By default venus hardware has
alignments as 128x32, but NV12 was defined differently to meet
various usecases. Compressed NV12 has always been aligned as 128x32,
hence not needed to override the default alignment.

media: venus: venc: Fix potential null pointer dereference on pointer fmt

2021-08-04T12:43:52+00:00

Currently the call to find_format can potentially return a NULL to
fmt and the nullpointer is later dereferenced on the assignment of
pixmp->num_planes = fmt->num_planes.  Fix this by adding a NULL pointer
check and returning NULL for the failure case.
