Tom StDenis was working on a similar patch for amdgpu as well, please
make sure that your work doesn't conflict with his.
Apart from that looks good to me. But I would prefer this to be split up
per driver, cause I can't really give my rb on this patch when it
touches drivers all over the place.
On the other hand feel free to add my Acked-by and merge it as general
cleanup through Dave directly.
Regards,
Christian.
