[PATCH v2 0/2] drm/drm_crtc: dma_fence_ops fixes

["André Draszik" <andre.draszik@linaro.org>]

Hi,

These patches fix two issues in the drm/drm_crtc driver. Initially I
was hitting the BUG_ON() in a scenario as explained in the commit
message of what is now the second patch in this series. For the reasons
outlines there, the BUG_ON() should just be removed.

After posting, sashiko.dev noticed another issue, that was previously
masked by the now-removed BUG_ON(). Since we can't have a loud BUG() be
replaced with silent data corruption or worse, I've also added a patch
to address this issue highlighted by sashiko.dev. I believe its
observation and analysis to be correct.

Cheers,
Andre'
