From: Lukas Wunner <lu...@wunner.de>

Rafael Antognolli's new DRM_DP_AUX_CHARDEV feature causes a WARN_ON
if drm_dp_aux->dev == drm_connector->kdev and drm_dp_aux_unregister()
is called after drm_connector_unregister(). radeon is the only driver
affected by this besides i915. (amdgpu calls drm_dp_aux_unregister()
before drm_connector_unregister().)
