Merge tag 'drm-misc-fixes-2020-12-03' of git://anongit.freedesktop.org/drm/drm-misc into drm-fixes
One bridge fix for OMAP, one for a race condition in a panel, two for uninitialized variables in rockchip and nouveau, and two fixes for mxsfb to fix a regression with modifiers and a fix for a fence synchronization issue.
