Merge tag 'drm-fixes-2024-12-07' of https://gitlab.freedesktop.org/drm/kernel

Pull drm fixes from Dave Airlie:
 "Pretty quiet week which is probably expected after US holidays, the
  dma-fence and displayport MST message handling fixes make up the bulk
  of this, along with a couple of minor xe and other driver fixes.

  dma-fence:
   - Fix reference leak on fence-merge failure path
   - Simplify fence merging with kernel's sort()
   - Fix dma_fence_array_signaled() to ensure forward progress

  dp_mst:
   - Fix MST sideband message body length check
   - Fix a bunch of locking/state handling with DP MST msgs

  sti:
   - Add __iomem for mixer_dbg_mxn()'s parameter

  xe:
   - Missing init value and 64-bit write-order check
   - Fix a memory allocation issue causing lockdep violation

  v3d:
   - Performance counter fix"
