These two patches need to be reverted since they were part (3/4 & 4/4)
of a series, that was partially (1/4 + 2/4) on the linux-media tree.
These two patches depend on the patches in the media tree, and will
not build without them, which leaves linux-drm-misc-next in a broken
state. Let's revert the two latter patches until rc1 has been branched
and the dependency wont cause issues any more.
