First I want to make sure: we are talking about commit
60b4667275b60d92c760d48df95f5b80bbcfde6e? Because I don't see
cacc2a81b9872aa8830353110b1252021f124ae8 around.

    drm: Add drm_atomic_get_(old|new)_connector_for_encoder() helpers

    commit 1b27fbdde1df172dba604855c45078d741f8c858 upstream.

    Add functions to the atomic core to retrieve the old and new
    connectors associated with an encoder in a drm_atomic_state. This
    is useful for encoders and bridges that need to access the
    connector, for instance for the drm_display_info.
