[PATCH v3 0/2] Stabilize use of vblank_refcount

[Paloma Arellano <quic_parellan@xxxxxxxxxxx>]

There is currently a race condition occuring when accessing
vblank_refcount. Therefore, vblank irq timeouts may occur.

Avoid any vblank irq timeouts by stablizing the use of vblank_refcount.

Changes from prior versions:
   v2: - Slightly changed wording of patch #2 commit message
   v3: - Mistakenly did not change wording of patch #2 in last version.
         It is done now.

Paloma Arellano (2):
  drm/msm/dpu: Modify vblank_refcount if error in callback
  drm/msm/dpu: Add mutex lock in control vblank irq
