Subject: netfilter: ip6t_SYNPROXY: unnecessary to check whether ip6_route_output returns NULL
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=d2b484b577776f3c6f4d52505b27bad27ea1fe00;p=linux-beck.git

netfilter: ip6t_SYNPROXY: unnecessary to check whether ip6_route_output returns NULL

ip6_route_output() will never return a NULL pointer, so there's no need
to check it.
