Merge tag 'drm-fixes-2020-10-09' of git://anongit.freedesktop.org/drm/drm
Pull amdgpu drm fixes from Dave Airlie:
"Fixes trickling in this week.
Alex had a final fix for the newest GPU they introduced in rc1, along
with one build regression and one crasher fix.
Cross my fingers that's it for 5.9:
- Fix a crash on renoir if you override the IP discovery parameter
- Fix the build on ARC platforms
- Display fix for Sienna Cichlid"
