Pull drm fixes from Dave Airlie:
 "Pretty quiet week on the fixes front, 4 amdgpu and one i915 fix.

  I think there might be a few misc fbdev ones outstanding, but I'll see
  if they are necessary and pass them on if so.

  amdgpu:

   - Disable ASPM for VI boards on ADL platforms

   - S0ix DCN3.1 display fix

   - Resume regression fix

   - Stable pstate fix

  i915:

   - fix for kernel memory corruption when running a lot of OpenCL tests
     in parallel"
