From: Hangbin Liu <liuhangbin@xxxxxxxxx> [ Upstream commit 004b39427f945696db30abb2c4e1a3856ffff819 ] Previously we will return directly if (!rt || !rt->fib6_nh.fib_nh_gw_family) in function rt6_probe(), but after commit cc3a86c802f0 ("ipv6: Change rt6_probe to take a fib6_nh"), the logic changed to return if there is fib_nh_gw_family. Fixes: cc3a86c802f0 ("ipv6: Change rt6_probe to take a fib6_nh") Signed-off-by: Hangbin Liu <liuhangbin@xxxxxxxxx> Reviewed-by: David Ahern <dsahern@xxxxxxxxx> Signed-off-by: David S.
