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
