If omap-alsa-mixer.c is compiled as module,

CONFIG_SENSORS_TLV320AIC23_MODULE is missing:
     CC [M]  sound/arm/omap-alsa-mixer.o
sound/arm/omap-alsa-mixer.c: In function SND_OMAP_WRITE'
sound/arm/omap-alsa-mixer.c: In function MIXER_NAME' undeclared (first
use in this function)
sound/arm/omap-alsa-mixer.c:487: error: (Each undeclared identifier is
reported only once
sound/arm/omap-alsa-mixer.c:487: error: for each function it appears in.)

Btw: omap-alsa-mixer.c will not compile if CONFIG_SENSORS_TLV320AIC23 or
CONFIG_SENSORS_TLV320AIC23_MODULE aren't defined. May be this ifdef
should be removed?
