Sorry, I accidentally replied to this in private and then Alex replied
but it all got lost.

He said he was going to change the eeepc use KEY_RFKILL instead of
KEY_WLAN to switch all types...

So I guess what this change really does is make __rfkill_switch_all() be
able to not only switch all devices of a given type, but also be able to
switch all devices of all types.

Alex, can you please rewrite the commit log to make that clearer?
