Merge tag 'drm-misc-fixes-2019-01-17' of git://anongit.freedesktop.org/drm/drm-misc into drm-fixes 



drm-misc-fixes for v5.0-rc3:
- Add missing calls to of_node_put to sun4i, meson, and rockchip.
- Drop unimplemented prime callbacks in virtio and qxl, so support
  for prime is not advertised on those drivers.
- Fix mode switching regression in meson.
