Merge tag 'drm-fixes-2020-01-03' of git://anongit.freedesktop.org/drm/drm
Pull drm fixes from Dave Airlie:
"New Years fixes! Mostly amdgpu with a light smattering of arm
graphics, and two AGP warning fixes.
Quiet as expected, hopefully we don't get a post holiday rush.
agp:
- two unused variable removed
amdgpu:
- ATPX regression fix
- SMU metrics table locking fixes
- gfxoff fix for raven
- RLC firmware loading stability fix
mediatek:
- external display fix
- dsi timing fix
sun4i:
- Fix double-free in connector/encoder cleanup (Stefan)
maildp:
- Make vtable static (Ben)"
