What is an "AIC34b_dummy (block B)"? You probably want to split it out
into a separate patch.

Could you please explain what the issue here is? A description of the
hardware would go a long way here.

EXPORT_SYMBOL_GPL().

Some defines for the mode (instead of magic numbers) would be nice).

Why is this being exported?

This looks like it ought to be pushed down into some other driver?
