> Move final cleanups to qxl_drm_release() callback.
Can you explain in the commit why this is better or preferable?
> Add drm_atomic_helper_shutdown() call to qxl_pci_remove().
I suppose this is to replace the former manual cleanup calls,
which were moved to qxl_drm_release, I think this could be
added in the commit message ("why"), I don't see much value
in describing "how" this was done.

Typo: releaseing -> releasing
Why not putting this in a separate commit? Was this behaviour
changed? It does not seem so to me.
