[PATCH 0/2] Stabilize use of vblank_refcount

[Paloma Arellano]

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.

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