Subject: [PATCH] netfilter: ip_tables: remove useless variable assignment in get_info()

From: "Gustavo A. R. Silva" <[email-masked]>
Date: Mon, 26 Jun 2017 17:34:28 -0500

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.
