Please keep the todo item that it needs to be converted to atomic. And
tbh, it's probably faster if you just submit it to dri-devel, assuming you
have time to work on it. For small drivers we tend to be fairly quick in
getting them into good enough shape.

Staging is also a major pain for drm subsystem refactorings, I really,
really, really prefer we don't add more than the vbox pain we have
already.
