Subject: net/ipv4: Remove unused variable in route.c
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=1bcdca3ffbbbed0d09b46cf4263ed2593a418375;p=openwrt%2Fstaging%2Fblogic.git

net/ipv4: Remove unused variable in route.c

int rc is unmodified after initalization in net/ipv4/route.c, this patch simply cleans up that variable and returns 0.

This was found with coccicheck M=net/ipv4/ on linus' tree.
