Subject: [NET]: Fix sparse warnings
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=20380731bc2897f2952ae055420972ded4cd786e;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

[NET]: Fix sparse warnings

Of this type, mostly:

CHECK   net/ipv6/netfilter.c
net/ipv6/netfilter.c:96:12: warning: symbol 'ipv6_netfilter_init' was not declared. Should it be static?
net/ipv6/netfilter.c:101:6: warning: symbol 'ipv6_netfilter_fini' was not declared. Should it be static?
