2644 * each stream. substreams = 0 indicates that the stream doesn't exist.
2645 * When rates and/or formats are zero, the supported values are queried
2646 * from the given nid. The nid is used also by the default ops.prepare
2647 * and ops.cleanup callbacks.
2648 *
2649 * The driver needs to call ops.open in its open callback. Similarly,
