[alsa-devel] usage of SOC_ENUM_SINGLE

I am trying to add an output control which is basically a switch between headset 
and earpiece. The H/W register for this asks me to write 0x40 for EP and 0x3 for 
enabling Headset

So I did this:

static const char *headset_switch_text[] = {
	"Earpiece", "HeadSet"

static const struct snd_kcontrol_new intel_msic_snd_controls[] = {	
SOC_ENUM_SINGLE(OUTEN, 0x43, 0x40, headset_switch_text),

Would this be the right thing, I am interpreting that 0x40 will be written for 
earpiece in above and 0x3 for headset
