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
