ALSA: usb-audio: uac1: Invalidate ctl on interrupt
When an interrupt occurs, the value of at least one of the belonging controls should have changed. To make sure they get re-read from device on the next read, invalidate the cache. This was correctly implemented for uac2 already, but missing for uac1. Signed-off-by: Julian Scheel <julian@jusst.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>
