Well, the problem is that the dependency with I2C is incomplete right
now. We may build ASOC=y and I2C=m, and you'll get unresolved symbols
due to call of I2C function from asoc.
I'm not sure what is the proper way to fix this. If the codec driver
supports non-I2C and can be built without it, the explicit dependency
on I2C is of course wrong.
