I think a variant of drm_atomic_set_fence_for_plane, which takes a
reservation obj (or a dma-buf and then derefs dma_buf->resv itself) would
be nice, so that drivers don't have to hand-roll sub-par fence waiting
code like this (it's e.g. not interruptible for blocking commits).

Anyway, patch itself looks good.
