From ec3f149017ef3fd21343b1dcec3589eec6ba5dd5 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Fri, 10 Jul 2009 02:45:38 +0200 Subject: [PATCH] cfg80211: fix a locking bug 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.
