What's my 'control data'? It's not used in the original codec patch.

The old way wants to go:

snd_soc_update_bits() -> snd_soc_read() -> ab8500_codec_read_reg()

quoted

When then calls back into the abx500.

So what 'control data' should I be storing in the codec struct?

You're supposed to use it for the data you use to call back into the
underlying I/O code.

I don't understand. What 'data'?

Surely if .read and .write are populated in 'struct 
snd_soc_codec_driver', then it should just call back into those?
