Subject: mac80211_hwsim: unregister genetlink family properly
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=2459cd876e2828dc63c19ea5dadf8a94a8f11244;p=linux-beck.git

mac80211_hwsim: unregister genetlink family properly

During hwsim_init_netlink(), we should call genl_unregister_family()
if failed on netlink_register_notifier() since the genetlink is
already registered.
