ALSA: opti-miro: fix OOPS if hardware is not detected
If a hardware is not detected there is a kernel crash due to not initialized snd_miro->aci pointer. This pointer is initialized after detection of the opti (miro) chip. This bug was introduced by patches to expose ACI mikser outside the snd-miro driver. Signed-off-by: Krzysztof Helt <krzysztof.h1@wp.pl> Signed-off-by: Takashi Iwai <tiwai@suse.de>
