Subject: net: ipv6: minor: use in6addr_any in token init
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=914faa147bd2d086ed7257ad785d74cfe48d30ad;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

net: ipv6: minor: use in6addr_any in token init

Since we check for !ipv6_addr_any(&in6_dev->token) in
addrconf_prefix_rcv(), make the token initialization on
device setup more intuitive by using in6addr_any as an
initializer.
