Right now dpms callbacks can still fiddle with the connector state, but it can only turn connectors off. This is remediated by only checking crtc->state->active when the connector is active, and ignore crtc->state->active when the connector is off. connectors_active is no longer checked, and will be removed later in this series together with dpms. Another check for !encoder->crtc is performed by check_encoder_state too, so it can be removed. Changes since v1: - Add commit message. - rename state to old_state. - Move deletion of mst_port check to mst patch. Changes since v2: - Fix a null pointer dereference on MST now hw readout is fixed.
