Merge tag 'drm-misc-fixes-2018-03-22' of git://anongit.freedesktop.org/drm/drm-misc into drm-fixes

Main change is a patch to reject getfb call for multiplanar framebuffers,
then we have a couple of error path fixes on the sun4i driver. Still on that
driver there is a clk fix and finally a mmap offset fix on the udl driver.
