Pull drm fixes from Dave Airlie:
 "Final week of fixes, lots of small amdgpu fixes, some i915 and xe
  fixes, the nouveau changes fix a recent regression and some laptop
  panel black screens, then a couple of other misc ones.

  It's probably a little busier than I'd like, but each fix seems fine.

  amdgpu:
   - PSR fix
   - Panel replay fixes
   - DML fix
   - vblank power fix
   - Fix video caps
   - SMU 14.0 fix
   - GPUVM fix
   - MES 12 fix
   - APU carve out fix
   - DC vbios fix
   - NBIO fix

  i915:
   - Don't load GSC on ARL-H and ARL-U if too old FW
   - Avoid potential OOPS in enabling/disabling TV output

  xe:
   - Fix unlock on exec ioctl error path
   - Fix hibernation on LNL due to ggtt getting lost
   - Fix missing runtime PM in OA release

  bridge:
   - tc358768: Fix DSI command tx

  nouveau:
   - Fix GSP AUX error handling
   - dp: Handle retires for AUX CH transfers with GSP
   - fw: Sync DMA after setup

  panthor:
   - Fix partial BO mappings to GPU

  rockchip:
   - vop: Avoid null-ptr deref in plane-state check

  vmwgfx:
   - Avoid null-ptr deref in surface creation"
