Merge tag 'drm-misc-next-2016-11-29' of git://anongit.freedesktop.org/git/drm-misc into drm-next
Big thing is that drm-misc is now officially a group maintainer/committer model thing, with MAINTAINERS suitably updated. Otherwise just the usual pile of misc things all over, nothing that stands out this time around. * tag 'drm-misc-next-2016-11-29' of git://anongit.freedesktop.org/git/drm-misc: (33 commits) drm: Introduce drm_framebuffer_assign() drm/bridge: adv7511: Enable the audio data and clock pads on adv7533 drm/bridge: adv7511: Add Audio support drm/edid: Consider alternate cea timings to be the same VIC drm/atomic: Constify drm_atomic_crtc_needs_modeset() drm: bridge: dw-hdmi: add ASoC dependency drm: Fix shift operations for drm_fb_helper::drm_target_preferred() drm: Avoid NULL dereference for DRM_LEGACY debug message drm: Use u64_to_user_ptr() helper for blob ioctls drm: Fix conflicting macro parameter in drm_mm_for_each_node_in_range() drm: Fixup kernel doc for driver->gem_create_object drm/hisilicon/hibmc: mark PM functions __maybe_unused drm/hisilicon/hibmc: Checking for NULL instead of IS_ERR() drm: bridge: add DesignWare HDMI I2S audio support drm: Check against color expansion in drm_mm_reserve_node() drm: Define drm_mm_for_each_node_in_range() drm/doc: Fix links in drm_property.c MAINTAINERS: Add link to drm-misc documentation vgaarb: use valid dev pointer in vgaarb_info() drm/atomic: Unconfuse the old_state mess in commmit_tail ...
