[ALSA] ac97 - Suppress power-saving mode on non-supporting drivers
Don't enable power-saving mode on drivers that don't support it. The supporting drivers set AC97_SCAP_POWER_SAVE to scaps at creation of ac97 instance. Currently enable on the following drivers: intel8x0, intel8x0m, atiixp, atiixp-modem, via82xx and via82xx-modem. Also, a bit clean up of power-saving stuff: - Don't create an own workq - Remove superfluous ifdefs Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@suse.cz>
