Subject: [patch net-next 1/4] net: call call_netdevice_unregister_net_notifiers from unregister
Date: Fri, 20 Dec 2019 13:35:39 +0100 [thread overview]
Message-ID: <20191220123542.26315-2-jiri@resnulli.us> (raw)
In-Reply-To: <20191220123542.26315-1-jiri@resnulli.us>
From: Jiri Pirko <jiri@mellanox.com>
The function does the same thing as the existing code, so rather call
call_netdevice_unregister_net_notifiers() instead of code duplication.
