[PATCH] ASoC: davinci: vcif must be a module if SND_DAVINCI_SOC is

From: Arnd Bergmann
Date: Mon Sep 29 2014 - 11:32:55 EST

It is possible to configure a kernel with SND_DAVINCI_SOC=m and
SND_DM365_VOICE_CODEC=y, which results in a link error:

sound/built-in.o: In function `davinci_vcif_probe':
sound/soc/davinci/davinci-vcif.c:223: undefined reference to `davinci_soc_platform_register'

The best way to avoid this is to make SND_DM365_VOICE_CODEC
a tristate option that depends on SND_DAVINCI_SOC, so it
can only be a module or disabled when the base driver is
a loadable module

Say Y if you want to add support for AIC3101 audio codec
