From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>
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)
