From 96c87607ac8f9b0e641d11ba6e57f8ec0214ea1c Mon Sep 17 00:00:00 2001 From: Henrique de Moraes Holschuh Date: Sat, 2 Aug 2008 15:11:00 -0300 Subject: rfkill: introduce RFKILL_STATE_MAX While it is interesting to not add last-enum-markers because it allows gcc to warn us of switch() statements missing a valid state, we really should be handling memory corruption on a rfkill state with default clauses, anyway. So add RFKILL_STATE_MAX and use it where applicable. It makes for safer code in the long run. Signed-off-by: Henrique de Moraes Holschuh Acked-by: Ivo van Doorn Signed-off-by: John W.
