From 9961920199ec88d6b581d3e38502088935925c04 Mon Sep 17 00:00:00 2001 From: Henrique de Moraes Holschuh Date: Sat, 2 Aug 2008 15:10:58 -0300 Subject: 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 Acked-by: Ivo van Doorn Signed-off-by: John W.
