5.1 backport request

[Daniel Vetter]

Hi stable team,

Please backport dbb92471674a ("Revert "drm: allow render capable
master with DRM_AUTH ioctls"") to 5.1, we accidentally forgot the Cc:
stable and Fixes: line for that revert. Thanks to Michel for spotting
this.

Dave, for next time around there's $ dim fixes $broken_sha1

Thanks, Daniel
