This patch still seems to do two totally separate things:
1) pass intel_atomic_State all over (for which there was another
   patch in the series as well?)
2) this intel_crtc_copy_color_blobs() change

I would split these up because the commit message doesn't
even mention the second change.

Each part looks fine on its own so with a proper split they are
