Merge tag 'drm-next-2021-05-10' of git://anongit.freedesktop.org/drm/drm
Pull drm fixes from Dave Airlie:
"Bit later than usual, I queued them all up on Friday then promptly
forgot to write the pull request email. This is mainly amdgpu fixes,
with some radeon/msm/fbdev and one i915 gvt fix thrown in.
amdgpu:
- MPO hang workaround
- Fix for concurrent VM flushes on vega/navi
- dcefclk is not adjustable on navi1x and newer
- MST HPD debugfs fix
- Suspend/resumes fixes
- Register VGA clients late in case driver fails to load
- Fix GEM leak in user framebuffer create
- Add support for polaris12 with 32 bit memory interface
- Fix duplicate cursor issue when using overlay
- Fix corruption with tiled surfaces on VCN3
- Add BO size and stride check to fix BO size verification
radeon:
- Fix off-by-one in power state parsing
- Fix possible memory leak in power state parsing
msm:
- NULL ptr dereference fix
fbdev:
- procfs disabled warning fix
i915:
- gvt: Fix a possible division by zero in vgpu display rate
calculation"
