Yes, I know this.

But you're implementing hacks instead of fixing the problem.

Btw, you inserted the machine_is() into the tosa driver, but
wm97xx driver registers unconditionally. That could be a problem
when wm97xx loads first, and then you try to load the tosa_battery
module on tosa machine.

Let's insert machine_is() hack into the wm97xx driver as well?
