- * snd_hda_build_pcms - build PCM information
- * @bus: the BUS
- *
- * Create PCM information for each codec included in the bus.
- *
- * The build_pcms codec patch is requested to set up codec->num_pcms and
- * codec->pcm_info properly. The array is referred by the top-level driver
- * to create its PCM instances.
- * The allocated codec->pcm_info should be released in codec->patch_ops.free
- * callback.
- *
- * At least, substreams, channels_min and channels_max must be filled for
- * each stream. substreams = 0 indicates that the stream doesn't exist.
- * When rates and/or formats are zero, the supported values are queried
- * from the given nid. The nid is used also by the default ops.prepare
- * and ops.cleanup callbacks.
- *
- * The driver needs to call ops.open in its open callback. Similarly,
- * ops.close is supposed to be called in the close callback.
- * ops.prepare should be called in the prepare or hw_params callback
- * with the proper parameters for set up.
- * ops.cleanup should be called in hw_free for clean up of streams.
- *
- * This function returns 0 if successful, or a negative error code.
