Merge tag 'topic/drm-misc-2016-03-22' of git://anongit.freedesktop.org/drm-intel into drm-next

Browse source 
Bunch of small fixupes all over. Plus a dma-buf patch that Sumit asked me
to cherry-pick since that's the only one he had in his tree.

There's a sparse issue outstanding in the color mgr stuff, but Lionel is
still working on something that actually appeases sparse.

  dma-buf/fence: fix fence_is_later v2
