Merge tag 'drm-next-2022-01-07' of git://anongit.freedesktop.org/drm/drm
Pull drm updates from Dave Airlie:
"Highlights are support for privacy screens found in new laptops, a
bunch of nomodeset refactoring, and i915 enables ADL-P systems by
default, while starting to add RPL-S support.
vmwgfx adds GEM and support for OpenGL 4.3 features in userspace.
Lots of internal refactorings around dma reservations, and lots of
driver refactoring as well.
