hda_get_autocfg_input_label - Get a label for the given input

Get a label for the given input pin defined by the autocfg item. Unlike hda_get_input_pin_label(), this function checks all inputs defined in autocfg and avoids the redundant mic/line prefix as much as possible.

snd_hda_get_pin_label - Get a label for the given I/O pin

Get a label for the given pin. This function works for both input and output pins. When is given as non-NULL, the function tries to get an optimized label using hda_get_autocfg_input_label().

This function tries to give a unique label string for the pin as much as possible. For example, when the multiple line-outs are present, it adds the channel suffix like "Front", "Surround", etc (only when is given). If no unique name with a suffix is available and is non-NULL, the index number is stored in the pointer.
