Subject: [IP6TUNNEL]: Use proper net instead of init_net stubs.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=2f7f54b725f1a93f0a4daace1a924bee382b33b6;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

[IP6TUNNEL]: Use proper net instead of init_net stubs.

All the ip_route_output_key(), dev_get_by_...() and ipv6_chk_addr()
calls are now stubbed with init_net.

Fortunately, all the places already have where to get the proper
net from.
