Greg doesn't accept patches as attachments and during the merge window
(which ends today).  I've just resubmitted your patch as part of a
2-patch series, together with a patch of mine which goes on top of yours:

https://lore.kernel.org/linux-serial/85fa3323ba8c307943969b7343e23f34c3e652ba.1642909284.git.lukas@wunner.de/

(I sent your patch twice because I botched the Date header the first time
around, sorry about that.)

Note that you still get patch authorship (and thus credit for the patch)
even though I submitted it, due to the From: line at the top of the
message body.

It just means that you need to add the two above-quoted tags to the
commit message.  The maintainers of stable kernels use them to
determine which patches need to be backported to which kernel
releases.  I've fixed up the commit message of your patch with
the missing tags, no problem.

And "cc the author of the offending commit" just means that when
posting the patch, it is customary to send a copy of the e-mail
to the author of the commit you're fixing, which is Lino in this
case, as he authored 8d479237727c.

Thanks,

Lukas
