That's what I just looked at, it's in mainline as well. I briefly considered
backporting that fix manually, but was not sure why radeon is apparently not
a "modesetting driver" and figured I'd rather wait for someone who understands
drm better than me.

Agreed - using 4.18.11 just fine right now without it. :)
