Make sure we get an event when the regulator is disabled so we know we have to sync the cache afterwards.
Note that the whole callback thing is more important for things with idle_bias_off (which might get the regulators powered down at runtime) than for other things which don't go down to _BIAS_OFF at runtime so would only trigger the callback on suspend anyway.
Not a problem doing the work, it'll just be unlikely to get called at runtime.
Minor stylistic changes.
Always split different things out into separate patches unless they overlap with each other a lot.

Jarkko's way of doing this was a bit nicer, but both aren't great :(

It's better to restructure the code so that the compiler is able to follow the control flow and see that there's no uninitialised access - this sort of change will just shut up legitimate warnings as well. Some of the other CODEC drivers (wm8400 is one) have had similar changes which seem to do the trick.
