Merge tag 'drm-misc-fixes-2018-02-28' of git://people.freedesktop.org/drm-misc into drm-fixes

Two regression fixes here: a fb format regression on nouveau and a 4.16-rc1
regression with on LVDS with one sun4i device. Plus a sun4i and  a virtio-gpu
fixes.

* tag 'drm-misc-fixes-2018-02-28' of git://people.freedesktop.org/drm-misc:
  virtio-gpu: fix ioctl and expose the fixed status to userspace.
  drm/sun4i: Protect the TCON pixel clocks
  drm/sun4i: Enable the output on the pins (tcon0)
  drm/nouveau: prefer XBGR2101010 for addfb ioctl
