Please sign off using your real name, which is commonly of the form:
Signed-off-by: First Last <me@...mple.com>
Please consider targeting this against 'net' as it appears to be a bug fix.
Subject: [PATCH net] ...
If not, please target the patch against net-next.
If so, please consider using including a fixes tag, immediately
above your Signed-off-by (and any other) tags.
This may be the correct tag, but I'm not completely sure.
Fixes: e0a4b99773d3 ("hsr: use upper/lower device infrastructure")

I think this needs to jump to an unwind label.
goto fail_upper_dev_link;
But I also think the unwind label should be renamed.
to reflect what they do, rather than where they are called from.
