I should have pushed the 3 udmabuf fixes to drm-misc-fixes instead of
drm-misc-next but didn't do it because it was after RC6 and I didn't want
to make any mistakes (accidentally). However, if the drm-misc maintainers
(CC'd) are ok with it, I have no problem if they can cherry-pick these
udmabuf patches to drm-misc-next-fixes so that they can make it into 7.1.

Thanks,
Vivek
