Merge tag 'drm-fixes-2024-06-01' of https://gitlab.freedesktop.org/drm/kernelHEADmaster

Pull drm fixes from Dave Airlie:
 "This is the weekly fixes. Lots of small fixes across the board, one
  BUG_ON fix in shmem seems most important, otherwise amdgpu, i915, xe
  mostly with small fixes to all the other drivers.

  shmem:
   - fix BUG_ON in COW handling
   - warn when trying to pin imported objects

  buddy:
   - fix page size handling

  dma-buf:
   - sw-sync: Don't interfere with IRQ handling
   - fix kthreads-handling error path

  i915:
   - fix a race in audio component by registering it later
   - make DPT object unshrinkable to avoid shrinking when framebuffer
     has not shrunk
   - fix CCS id calculation to fix a perf regression
   - fix selftest caching mode
   - fix FIELD_PREP compiler warnings
   - fix indefinite wait for GT wakeref release
   - revert overeager multi-gt pm reference removal

  xe:
   - pcode polling timeout change
   - fix for deadlocks for faulting VMs
   - error-path lock imbalance fix

  amdgpu:
   - RAS fix
   - fix colorspace property for MST connectors
   - fix for PCIe DPM
   - silence UBSAN warning
   - GPUVM robustness fix
   - partition fix
   - drop deprecated I2C_CLASS_SPD

  amdkfd:
   - revert unused changes for certain 11.0.3 devices
   - simplify APU VRAM handling

  lima:
   - fix dma_resv-related deadlock in object pin

  msm:
   - remove build-time dependency on Python 3.9

  nouveau:
   - nvif: Fix possible integer overflow

  panel:
   - lg-sw43408: Select DP helpers; Declare backlight ops as static
   - sitronix-st7789v: Various fixes for jt240mhqs_hwt_ek_e3 panel

  panfrost:
   - fix dma_resv-related deadlock in object pin"
