From a1699b75a1db31a1da2f0fc610ee696d02a19280 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Fri, 30 Jul 2010 16:46:07 +0200 Subject: mac80211: unify scan and work mutexes Having both scan and work mutexes is not just a bit too fine grained, it also creates issues when there's code that needs both since they then need to be acquired in the right order, which can be hard to do. Therefore, use just a single mutex for both. Signed-off-by: Johannes Berg Signed-off-by: John W.
