There were no targets still actively using Linux 5.4.

-Subject: [PATCH] wireguard: selftests: initalize ipv6 members to NULL to
- squelch clang warning
-
-commit 4fed818ef54b08d4b29200e416cce65546ad5312 upstream.
-
-Without setting these to NULL, clang complains in certain
-configurations that have CONFIG_IPV6=n:

-We silence this warning by setting the variables to NULL as the warning
-suggests.
