550 * Get a label for the given pin. This function works for both input and

552 * an optimized label using hda_get_autocfg_input_label().
553 *
554 * This function tries to give a unique label string for the pin as much as
555 * possible. For example, when the multiple line-outs are present, it adds
556 * the channel suffix like "Front", "Surround", etc (only when @cfg is given).
557 * If no unique name with a suffix is available and @indexp is non-NULL, the
558 * index number is stored in the pointer.
