Subject: [PATCH] cfg80211: fix a locking bug
Date: Fri, 10 Jul 2009 02:45:38 +0200	[thread overview]
Message-ID: <1247186738.1905.15.camel@johannes.local> (raw)

The cfg80211_sme_disassoc() function is already holding
a lock here that cfg80211_mlme_deauth() would take, so
it needs to use __cfg80211_mlme_deauth() instead.
