Merge tag 'drm-fixes-2023-08-18-1' of git://anongit.freedesktop.org/drm/drm

Pull drm fixes from Dave Airlie:
 "Regular enough week, mostly the usual amdgpu and i915 fixes.  Also
  qaic, nouveau, qxl and a revert for an EDID patch that had some side
  effects, along with a couple of panel fixes.

  edid:
   - revert mode parsing fix that had side effects.

  i915:
   - Fix the flow for ignoring GuC SLPC efficient frequency selection
   - Fix SDVO panel_type initialization
   - Fix display probe for IVB Q and IVB D GT2 server

  nouveau:
   - fix use-after-free in connector code

  qaic:
   - integer overflow check fix
   - fix slicing memory leak

  panel:
   - fix JDI LT070ME05000 probing
   - fix AUO G121EAN01 timings

  amdgpu:
   - SMU 13.x fixes
   - Fix mcbp parameter for gfx9
   - SMU 11.x fixes
   - Temporary fix for large numbers of XCP partitions
   - S0ix fixes
   - DCN 2.0 fix

  qxl:
   - fix use after free race in dumb object allocation"
