But intel_connector alone is fine. Agreed with this and the rest later. They are however separate changes than what's the commit describes. For both author and reviewer it would be better to do these in separate patches (even though it's good that you noticed this now).

Follow the canonical way in intel_dp_mst.c, referencing a connector only via a struct intel_connector pointer and naming this pointer 'connector' instead of 'intel_connector', the only exception being the casting of a drm_connector function parameter pointer to intel_connector, calling the drm_connector pointer _connector.
