ALSA: usb-audio: Save mixer status only once at suspend The suspend callback of usb-audio driver may be called multiple times per suspend when multiple USB interfaces are bound to a single sound card instance. In such a case, it's superfluous to save the mixer values multiple times. This patch fixes it by checking the counter. Signed-off-by: Takashi Iwai <tiwai@suse.de>
