1811 * @bus: the BUS
1812 *
1813 * Create PCM information for each codec included in the bus.
1814 *
1815 * The build_pcms codec patch is requested to set up codec->num_pcms and
1816 * codec->pcm_info properly. The array is referred by the top-level driver
1817 * to create its PCM instances.
1818 * The allocated codec->pcm_info should be released in codec->patch_ops.free
1819 * callback.
1820 *
1821 * At least, substreams, channels_min and channels_max must be filled for
1822 * each stream. substreams = 0 indicates that the stream doesn't exist.
1823 * When rates and/or formats are zero, the supported values are queried
1824 * from the given nid. The nid is used also by the default ops.prepare
1825 * and ops.cleanup callbacks.
1826 *
1827 * The driver needs to call ops.open in its open callback. Similarly,
1828 * ops.close is supposed to be called in the close callback.
1829 * ops.prepare should be called in the prepare or hw_params callback
1830 * with the proper parameters for set up.
1831 * ops.cleanup should be called in hw_free for clean up of streams.
1832 *
1833 * This function returns 0 if successfull, or a negative error code.
