Merge tag 'topic/drm-fixes-2015-07-16' of git://anongit.freedesktop.org/drm-intel into drm-fixes
Ok next attempt at drm-fixes pull. Big thing really is just the compat32 one for addfb2.1. * tag 'topic/drm-fixes-2015-07-16' of git://anongit.freedesktop.org/drm-intel: drm: Provide compat ioctl for addfb2.1 Documentation: drm: Fix tablulation in KMS properties table drm: add a check for x/y in drm_mode_setcrtc drm/rockchip: use drm_gem_mmap helpers
