Don't change things that you don't describe in your changelog and that are not needed for your change. thanks, greg k-h

Since commit fc7a6209d571 ("bus: Make remove callback return void") forces bus_type::remove be void-returned, it doesn't make much sense for any bus based driver implementing remove callbalk to return non-void to its caller. This change is for ac97 bus based drivers.
