snd_ac97_tune_hardware - tune up the hardware

int snd_ac97_tune_hardware(struct snd_ac97 *  ac97 , struct ac97_quirk *  quirk , const char *  override );

ac97
    the ac97 instance

quirk
    quirk list

override
    explicit quirk value (overrides the list if non-NULL)

Do some workaround for each pci device, such as renaming of the headphone (true line-out) control as « Master ». The quirk-list must be terminated with a zero-filled entry.

Zero if successful, or a negative error code on failure.
