We need the connector to\nbe set before that. Unlike in legacy cases with flag\n!DRM_BRIDGE_ATTACH_NO_CONNECTOR, we do not have connector initialised\nin bridge_attach(), so add the mhdp-\u003econnector_ptr in device structure\nto handle both cases with DRM_BRIDGE_ATTACH_NO_CONNECTOR and\n!DRM_BRIDGE_ATTACH_NO_CONNECTOR, set it in atomic_enable() earlier to\navoid possible NULL pointer dereference in recovery paths like\nmodeset_retry_fn() with the DRM_BRIDGE_ATTACH_NO_CONNECTOR flag set.",
