Merge tag 'topic/drm-misc-2016-03-22' of git://anongit.freedesktop.org/drm-intel into drm-next
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.
* tag 'topic/drm-misc-2016-03-22' of git://anongit.freedesktop.org/drm-intel:
dma-buf/fence: fix fence_is_later v2
dma-buf: Update docs for SYNC ioctl
drm: remove excess description
dma-buf, drm, ion: Propagate error code from dma_buf_start_cpu_access()
drm/atmel-hlcdc: use helper to get crtc state
drm/atomic: use helper to get crtc state
