From 98bd147d7903580ca5d5dfa0bc39c2d16714d84e Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Wed, 16 Mar 2016 14:29:08 +0100 Subject: [PATCH] wext: unregister_pernet_subsys() on notifier registration failure If register_netdevice_notifier() fails (which in practice it can't right now), we should call unregister_pernet_subsys(). Do that.
