 "These are the fixes from last week for the stuff merged in the merge
  window. It got a bunch of nouveau fixes for HDA audio on some new
  GPUs, some i915 and some amdpgu fixes.

  i915:
   - gvt: Fix one clang warning on debug only function
   - Use ARRAY_SIZE for coccicheck warning
   - Use after free fix for display global state.
   - Whitelisting context-local timestamp on Gen9 and two scheduler
     fixes with deps (Cc: stable)
   - Removal of write flag from sysfs files where ineffective

  nouveau:
   - HDMI/DP audio HDA fixes
   - display hang fix for Volta/Turing
   - GK20A regression fix.

  amdgpu:
   - Prevent hwmon accesses while GPU is in reset
   - CTF interrupt fix
   - Backlight fix for renoir
   - Fix for display sync groups
   - Display bandwidth validation workaround"
