Merge tag 'topic/drm-misc-2015-03-31' of git://anongit.freedesktop.org/drm-intel into drm-next
Final drm-misc pull for 4.0, just various things all over, including a few more important atomic fixes. btw I didn't pick up the vmwgfx patch from Ville's series, but one patch has one hunk touching vmwgfx and Thomas/Jakob didn't get around to ack it. I figured it's simple enough to be ok though. * tag 'topic/drm-misc-2015-03-31' of git://anongit.freedesktop.org/drm-intel: drm: line wrap DRM_IOCTL_DEF* macros drm/atomic: Don't try to free a NULL state drm/atomic: Clear crtcs, connectors and planes when clearing state drm: Rewrite drm_ioctl_flags() to resemble the new drm_ioctl() code drm: Use max() to make the ioctl alloc size code cleaner drm: Simplify core vs. drv ioctl handling drm: Drop ioctl->cmd_drv drm: Fix DRM_IOCTL_DEF_DRV() drm/atomic-helpers: Properly avoid full modeset dance drm: atomic: Allow setting CRTC active property drm: atomic: Expose CRTC active property drm: crtc_helper: Update hwmode before mode_set call drm: mode: Allow NULL modes for equality check drm: fb_helper: Simplify exit condition drm: mode: Fix typo in kerneldoc drm/dp: Print the number of bytes processed for aux nacks
