Fix a wrong error checking in exynos_drm_dma.c module.
In the exynos_drm_register_dma function, both arm_iommu_create_mapping()
and iommu_get_domain_for_dev() functions are expected to return NULL as
an error.
However, the error checking is performed using the statement
if(IS_ERR(mapping)), which doesn't provide a suitable error value.
So check if 'mapping' is NULL, and if it is, return -ENODEV.
This issue[1] was reported by Dan.
Changelog v1:
- fix build warning.

error: 'crtc' dereferencing possible ERR_PTR()
The return value of exynos_drm_crtc_get_by_type maybe ERR_PTR(-ENODEV),
which can not be used directly. Fix this by checking the return value
before using it.

[WHY]
Some eDP panels's ext caps don't write initial value cause the value of
dpcd_addr(0x317) is random. It means that sometimes the eDP will
clarify it is OLED, miniLED...etc cause the backlight control interface
is incorrect.
[HOW]
Add a new panel patch to remove sink ext caps(HDR,OLED...etc)

Invoke drm_plane_helper_funcs.end_fb_access before
drm_atomic_helper_commit_hw_done(). The latter function hands over
ownership of the plane state to the following commit, which might
free it. Releasing resources in end_fb_access then operates on undefined
state. This bug has been observed with non-blocking commits when they
are being queued up quickly.
Here is an example stack trace from the bug report. The plane state has
been free'd already, so the pages for drm_gem_fb_vunmap() are gone.
Unable to handle kernel paging request at virtual address 0000000100000049

drm_atomic_helper_commit_tail+0x90/0xa0
commit_tail+0x15c/0x188
commit_work+0x14/0x20
Fix this by running end_fb_access immediately after updating all planes
in drm_atomic_helper_commit_planes(). The existing clean-up helper
drm_atomic_helper_cleanup_planes() now only handles cleanup_fb.
For aborted commits, roll back from drm_atomic_helper_prepare_planes()
in the new helper drm_atomic_helper_unprepare_planes(). This case is
different from regular cleanup, as we have to release the new state;
regular cleanup releases the old state. The new helper also invokes
cleanup_fb for all planes.
The changes mostly involve DRM's atomic helpers. Only two drivers, i915
and nouveau, implement their own commit function. Update them to invoke
drm_atomic_helper_unprepare_planes(). Drivers with custom commit_tail
function do not require changes.
v4:
* fix documentation (kernel test robot)
v3:
* add drm_atomic_helper_unprepare_planes() for rolling back
* use correct state for end_fb_access
v2:
* fix test in drm_atomic_helper_cleanup_planes()

- Fix the lifecycle of a mutex in the pds variant driver such that a

Implement the release path to symmetrically destroy the mutex. Also
switch a different lock from spinlock to mutex as the code path has
the potential to sleep and doesn't need the spinlock context
otherwise (Brett Creeley)
- Fix an issue detected via randconfig where KVM tries to symbol_get an

unconditionally here, which resolves the problem and avoids churn
relative to a series pending for the next merge window which resolves
some of this symbol ugliness, but also fixes Kconfig dependencies

Pull probes fixes from Masami Hiramatsu:
- objpool: Fix objpool overrun case on memory/cache access delay
especially on the big.LITTLE SoC. The objpool uses a copy of object
slot index internal loop, but the slot index can be changed on
another processor in parallel. In that case, the difference of 'head'
local copy and the 'slot->last' index will be bigger than local slot
size. In that case, we need to re-read the slot::head to update it.
- kretprobe: Fix to use appropriate rcu API for kretprobe holder. Since
kretprobe_holder::rp is RCU managed, it should use
rcu_assign_pointer() and rcu_dereference_check() correctly. Also
adding __rcu tag for finding wrong usage by sparse.
- rethook: Fix to use appropriate rcu API for rethook::handler. The
same as kretprobe, rethook::handler is RCU managed and it should use
rcu_assign_pointer() and rcu_dereference_check(). This also adds
