ALSA: ak411x: Add PM helper functions
Define snd_ak4114_suspend() and snd_ak4114_resume() functions to handle PM properly, stopping and restarting the work at PM. Currently only ice1712/juli.c deals with the PM and ak4114, so fix the calls there appropriately. The same PM functions are defined in ak4113.c, too, although they aren't currently called yet (ice1712/quartet.c may be enhanced to support PM later). Acked-by: Jaroslav Kysela <perex@perex.cz> Tested-by: Pavel Hofman <pavel.hofman@ivitera.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
