Subject: [PATCH] ipvs: initialize 'ret' variable in do_ip_vs_set_ctl()
Date:   Fri,  2 Dec 2022 11:25:11 +0800
Message-Id: <20221202032511.1435-1-liqiong@nfschina.com>
Precedence: bulk

The 'ret' should need to be initialized to 0, in case
return a uninitialized value because no default process
for "switch (cmd)".
