a v2 with no changelog. From what I can tell the only difference is
"net: " in the Subject line which is not what I said in the last email.

Let me try again: There are 2 trees - net for bug fixes and net-next for
development (anything that is not a bug fix). Each patch should specify
which tree the patch is for by putting 'net' or 'net-next' in the
brackets ([]). This is a cleanup not a bug fix, so this patch should be:

[PATCH net-next] ipv6: remove unused local variable

and really that should be

[PATCH net-next] ipv6: remove unnecessary local variable

If you send more versions of a patch always put a changelog - a summary
of what is different in the current patch versus the previous ones.

No need to send another version of this patch unless you get a comment
requesting change, or the maintainers ask for a re-send.
