Documentation/rfkill.txt implied otherwise

You should:
- rfkill_allocate()
- modify rfkill fields (flags, name)
- modify state to the current hardware state (THIS IS THE ONLY TIME
YOU CAN ACCESS state DIRECTLY)
- rfkill_register()


Admittedly it doesn't say "and I promise not to gratuitously override
the state on registration". Buti t seems weird though, to override the
value on registration instead of just setting a default in
rfkill_allocate().

Thanks
