Did you miss a call to rfkill_force_state() on resume?


Conceivably. I didn't test the hibernation case.


Actually, normal boot doesn't preserve the setting either. Your commit
changes the behaviour from the rfkill state being persistent across
reboot / power off (as a bios setting), to being always enabled on
boot. It seems like a bad idea to me.


This is the behaviour of the rfkill core.

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
