Merge tag 'drm-fixes-2018-11-30' of git://anongit.freedesktop.org/drm/drm
Pull drm fixes from Dave Airlie:
"This weeks instalment of fixes. Looks fairly like business as usual
and everything seems to rolling along. There was one MST fix applied
and reverted in the misc tree, but otherwise nothing too strange in
here.
core:
- incorrect master setting on error fix
i915:
- only GVT fixes this week:
* one MOCS register load
* rpm lock fix
* use after free
rcar-du:
- regression fix for group start
amdgpu:
- DP MST fix
- GPUVM fix for huge pages
- RLC fix for vega20
ast:
- fix EDID reading stability
- ioreg free fix
meson:
- sleep in irq fix
- vblank fixes
- array boundary fix"
* tag 'drm-fixes-2018-11-30' of git://anongit.freedesktop.org/drm/drm:
drm/ast: fixed reading monitor EDID not stable issue

drm: set is_master to 0 upon drm_new_set_master() failure
drm/dp_mst: Skip validating ports during destruction, just ref
drm: rcar-du: Fix DU3 start/stop on M3-N
drm/amd/dm: Understand why attaching path/tile properties are needed
drm/amd/dm: Don't forget to attach MST encoders
drm/i915/gvt: Avoid use-after-free iterating the gtt list
