From e669ba2d06c6195662601956454ac959892f0762 Mon Sep 17 00:00:00 2001 From: Eliad Peller Date: Wed, 30 Apr 2014 16:14:24 +0300 Subject: mac80211: fix nested rtnl locking on ieee80211_reconfig ieee80211_reconfig already holds rtnl, so calling cfg80211_sched_scan_stopped results in deadlock. Use the rtnl-version of this function instead.
