Although we are maintainers of VKMS, it isn't recommended that we push
our own changes without even the Ack of another person. Please, read the
"drm-misc Committer Guidelines" [1].

I can ack patches 05/15, 07/15, and 09/15, but it would be more
beneficial for the community if you ask for an ack (from me or from the
DRM maintainers, which are always around), instead of saying that you
are going to commit the patches without any review.
