Some chips implement banked register ranges. This allows implementing
more registers than the limited 8-bit address space originally allows.
In order to access a register on these chips, you must first select
the proper bank. Add support for this mechanism to the i2c-stub driver
so that such chips can be emulated. All the bank settings are passed
as module parameters.

Thanks.
Would it make sense to use devm_ functions for memory allocations ?
That would simplify cleanup.
Sure, no objection from me.
If it was that simple :-(. We would have to convert the driver to a platform driver
to be able to do that, since the allocations happen from the initialization code,
not from a probe function. Guess we'll have to leave that for another day.
