Subject: [IPV4]: Fix issue reported by Coverity in ipv4/fib_frontend.c
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=9fcc2e8a752f7d3d889114221b67c459557823e9;p=openwrt%2Fstaging%2Fblogic.git

[IPV4]: Fix issue reported by Coverity in ipv4/fib_frontend.c

fib_del_ifaddr() dereferences ifa->ifa_dev, so the code already assumes that
ifa->ifa_dev is non-NULL, the check is unnecessary.
