I don't really know what is going on. If I go back to 4.17 and apply
my "fix". It doesn't work. I suppose my bisect didn't get me the right
commit. I probably never tested that the commit, from the bisect, was
actually bad. I was also a little lazy and did "bisect start
29dcea88779c856c7dc92040a0c01233263101d4
6da6c0db5316275015e8cc2959f12a17584aeb64 -- drivers/gpu/drm/amd".
I guess I'll try another bisect tomorrow on the entire tree, sorry for
the extra work.
