From ae5e0c773ca699ff2ae91bce7bd25e92b402c0a1 Mon Sep 17 00:00:00 2001 From: Andrea Claudi Date: Fri, 15 Feb 2019 17:51:48 +0100 Subject: [PATCH] ipvs: fix warning on unused variable MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit [ Upstream commit c93a49b9769e435990c82297aa0baa31e1538790 ] When CONFIG_IP_VS_IPV6 is not defined, build produced this warning: net/netfilter/ipvs/ip_vs_ctl.c:899:6: warning: unused variable ‘ret’ [-Wunused-variable] int ret = 0; ^~~ Fix this by moving the declaration of 'ret' in the CONFIG_IP_VS_IPV6 section in the same function. While at it, drop its unneeded initialisation.
