This patch fixes wrong return type when dt binding of bridge device failed.
If a board has a bridge device then of_graph_get_remote_port_parent function shouldn't be NULL. So this patch will return a proper error type so that the deferred probe isn't triggered. Changelog v2: - return -EINVAL if getting a port node failed.
