Subject: [PATCH] netfilter: ip_tables: remove useless variable assignment in get_info()
Date: Mon, 26 Jun 2017 17:34:28 -0500 [thread overview]
Message-ID: <20170626223428.GA11614@embeddedgus> (raw)
Value assigned to variable _ret_ at line 970 is overwritten either at
line 986 or 988, before it can be used. This makes such variable
assignment useless.
