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"
