#     Merge tag 'drm-fixes-2020-07-31' of git://anongit.freedesktop.org/drm/drm
#     
#     Pull more drm fixes from Dave Airlie:
#      "As mentioned previously this contains the nouveau regression fix.
#     
#       amdgpu had three fixes outstanding as well, one revert, an info leak
#       and use after free. The use after free is a bit trickier than I'd
#       like, and I've personally gone over it to confirm I'm happy that it is
#       doing what it says.
#     
#       nouveau:
#        - final modifiers regression fix
#     
#       amdgpu:
#        - Revert a fix which caused other regressions
#        - Fix potential kernel info leak
#        - Fix a use-after-free bug that was uncovered by another change in 5.7"
