Merge tag 'topic/drm-misc-2016-10-11' of git://anongit.freedesktop.org/drm-intel into drm-next

Just flushing out my -misc queue. Slightly important are the prime
refcount/unload fixes from Chris.

There's also the reservation stuff from Chris still pending, and Sumits
hasn't landed that yet. Might get another pull for that, but pls don't
hold up the main pull for it ;-)

* tag 'topic/drm-misc-2016-10-11' of git://anongit.freedesktop.org/drm-intel:
  drm/crtc: constify drm_crtc_index parameter
  drm: use the right function name in documentation
  drm: Release resources with a safer function
  drm: Fix up kerneldoc for new drm_gem_dmabuf_export()
  drm/bridge: Drop drm_connector_unregister and call drm_connector_cleanup directly
  drm/fb-helper: fix sphinx markup for DRM_FB_HELPER_DEFAULT_OPS
  drm/bridge: Add RGB to VGA bridge support
  drm/prime: Take a ref on the drm_dev when exporting a dma_buf
  drm/prime: Pass the right module owner through to dma_buf_export()
  drm/bridge: Call drm_connector_cleanup directly
  drm: simple_kms_helper: Add prepare_fb and cleanup_fb hooks
  drm: Release resources with a safer function
