Hm, I thought this was optional and it should be the default commit_tail
callback. Please remove (and if that doesn't work, pls type a core patch
to make it the default).

This is a bit backwards since you introduce the crtc helper only in a
later patch. Good reason to move the vblank stuff in there, and maybe even
fold the crtc helpers into the main kms patch :-)

Please use the new callbacks in drm_crtc_ops instead, these here are
deprecated.
