Merge tag 'drm-misc-fixes-2017-07-27' of git://anongit.freedesktop.org/git/drm-misc into drm-fixes
Core Changes: - dp: A few fixes in drm_dp_downstream_debug() (Chris) - rockchip: sanitize the Kconfig dependencies (fallout from EXTCON) (Arnd) - host1x: Free the iommu domain when attach_device fails (Paul) Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Arnd Bergmann <arnd@arndb.de> Cc: Paul Kocialkowski <contact@paulk.fr> * tag 'drm-misc-fixes-2017-07-27' of git://anongit.freedesktop.org/git/drm-misc: gpu: host1x: Free the IOMMU domain when there is no device to attach drm/rockchip: fix Kconfig dependencies drm/dp: Don't trust drm_dp_downstream_id() drm/dp: Fix read pointer for drm_dp_downsteam_debug()
