Thanks for the report; let me take a look and see if I can spot what's
going wrong.

I can patch this - but do I need to do to show that the patch is for
that specific bug report or anything?

What we do in such cases, usually, is add
Link: https://bugzilla.kernel.org/show_bug.cgi?id=214453
to the commit message, under the SOB chain.
Also, you probably also should give in a Fixes: tag the commit ID of the
patch your fix is for, so that your fix gets automatically backported to
stable.
I.e.:
Fixes: 12-char-sha1-abbrev ("Commit title")
Cc: <stable@vger.kernel.org>
HTH.
