Subject: ipv6: use ipv6_addr_any() helper
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=7996c799ae329fab1b9c8d475fd08883f0499ed9;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

ipv6: use ipv6_addr_any() helper

ipv6_addr_any() is a faster way to determine if an addr
is ipv6 any addr, no need to compute the addr type.
