Subject: [PATCH 12/18] ipv6/route: return if there is no fib_nh_gw_family

From: Hangbin Liu <[email-masked]>
Date: Wed, 20 Nov 2019 15:39:06 +0800

[ 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")
