I think this is the reason why Eduardo mentioned my name in the commit
log :-)

Yep, dummy driver is for block B of AIC34 which is basically dual AIC33
in a same package.

Eduardo, please correct me if I remember wrong  but block B of AIC34 is
not used as an codec as such but more like an amplifier and analogic
mixer with digital parts unused. So with this dummy driver the HW
features were easier to support than to develop multiple intance
support for codec drivers.
