Hmm, I'm afraid this may disable CONFIG_SND_SOC_TLV320AIC26 when
CONFIG_SND_SOC_OF_SIMPLE=n automatically, no?

Actually I proposed a wrong solution.  What I meant was the form using
"if" instead of "depends on":

config SND_SOC_TLV320AIC26
 	tristate "TI TLV320AIC26 Codec support" if SND_SOC_OF_SIMPLE
	...

In this way, the selectable item appears only when
CONFIG_SND_SOC_OF_SIMPLE is set.  The other dependencies remain as
they are.
