rfkill: add default global states (v2)
Add a second set of global states, "rfkill_default_states", to track the state that will be used when the first rfkill class of a given type is registered, and also to save "undo" information when rfkill_epo is called. Add a new exported function, rfkill_set_default(), which can be used by platform drivers to restore radio state saved by the platform across reboots or shutdown. Also, fix rfkill_epo to properly update rfkill_states, but still preserve a copy of the state so that we can undo the effect of rfkill_epo later if we want to. Add rfkill_restore_states() to restore rfkill_states from the copy. Signed-off-by: Henrique de Moraes Holschuh <hmh@hmh.eng.br> Acked-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W.
