From 60771780c27cbc93d0b78da0c7fd7a8a540b029e Mon Sep 17 00:00:00 2001 From: Michal Kazior Date: Fri, 29 Jun 2012 12:46:56 +0200 Subject: [PATCH] cfg80211: introduce cfg80211_stop_ap This functionality will be reused when interface is going down. Avoids code duplication. Also adds missing wdev locking.
