No, your AC97 driver shouldn't be doing any of this at all - it should
be leaving any enumeration of the hardware up to the machine driver and
the core. In so far as it is standardised the process for probing AC97
is something that can be implemented in terms of the operations exported
by the DAI so it should be done in the core for all AC97 DAIs. Where
standardised probing can't work it needs to be machine specific anyway.
