For formality, does this also imply a reviewed-by tag?

For merging propably best we wait for the backmerge and the push these in
through drm-misc-next-fixes.

Well for drm-misc-next-fixes drm-misc maintainers need to roll the tree
forward. Either way needs synchronization. Plus an ack from drm-intel
maintainers.
