   - Fix a possible segfault in bo validation error case
   - Delay removal of firmware framebuffer
   - Fix error when unloading

  amdkfd:
   - SVM fix when clearing vram
   - GC11 fix for multi-GPU

  i915:
   - Reserve enough fence slot for i915_vma_unbind_vsync
   - Fix potential use after free
   - Reset engines twice in case of reset failure
   - Use multi-cast registers for SVG Unit registers

  msm:
   - display:
   - doc warning fixes
   - dt attribs cleanups
   - memory leak fix
   - error handing in hdmi probe fix
   - dp_aux_isr incorrect signalling fix
   - shutdown path fix
   - accel:
   - a5xx: fix quirks to be a bitmask
   - a6xx: fix gx halt to avoid 1s hang
   - kexec shutdown fix
   - fix potential double free

  vmwgfx:
   - drop rcu usage to make code more robust

  virtio:
   - fix use-after-free in gem handle code

  nouveau:
   - drop unused nouveau_fbcon.c"
