This error comes from the upstream framework bug. In your config, ad193x is
built-in, SPI is built-in but i2c is compiled as a module, then you get the link
error. I will send a mail to Mark Brown to discuss this. I remember we split spi
and i2c drivers to solve this problem, but ASoC require us to place them
default m if I2C=m
default y if I2C=y
default y if SPI_MASTER=y
is not strong to handle this.

Check email loop: "bug in spi and i2c dual buses codecs"
Mark Brown think it is expected behavior. It's not been a practical problem -
the combination of audio built in and one of the buses modular is far
So looks like we can't configure kernel by this way.
We can either built-in all, or compile codec driver as module.

Modify build script to select I2C.
So close this bug.
