From: Ville Syrjälä ville.syrjala@linux.intel.com
Use drm_connector_for_each_possible_encoder() for iterating connector->encoder_ids[]. A bit more convenient not having to deal with the implementation details.
v2: Replace drm_for_each_connector_encoder_ids() with drm_connector_for_each_possible_encoder() (Daniel)
