Pull drm fixes from Dave Airlie:
 "Regular fixes for the week. Daniel has agreed to bring back the fbcon
  hw acceleration under a CONFIG option for the non-drm fbdev users, we
  don't advise turning this on unless you are in the niche that is old
  fbdev drivers, Since it's essentially a revert and shouldn't be high
  impact seemed like a good time to do it now.

  Otherwise, i915 and amdgpu fixes are most of it, along with some minor
  fixes elsewhere.

  fbdev:
   - readd fbcon acceleration

  i915:
   - fix DP monitor via type-c dock
   - fix for engine busyness and read timeout with GuC
   - use ALLOW_FAIL for error capture buffer allocs
   - don't use interruptible lock on error paths
   - smatch fix to reject zero sized overlays.

  amdgpu:
   - mGPU fan boost fix for beige goby
   - S0ix fixes
   - Cyan skillfish hang fix
   - DCN fixes for DCN 3.1
   - DCN fixes for DCN 3.01
   - Apple retina panel fix
   - ttm logic inversion fix

  dma-buf:
   - heaps: fix potential spectre v1 gadget

  kmb:
   - fix potential oob access

  mxsfb:
   - fix NULL ptr deref

  nouveau:
   - fix potential oob access during BIOS decode"
