At least one user in Debian (https://bugs.debian.org/992004) would be
happy to have those backported as well to the 5.10.y series (which we
will pick up).

So if Benjamin ack's this, this would be great to have in 5.10.y.
Sure, it is reasonable to pull it into 5.10. At the time it just seemed
to me that it was enough of a corner case to not bother.

Note that there was a somewhat related fix later on (for Qualcomm UCSI
firmware), which probably makes sense to pull in too then.

Including Bjorn into the CC list for that.

I feel that I should mention that I haven't actually tested this change, so
it's just conjecture on my part that it would fix my issue (though it does
seem to track pretty closely). I am happy to do that testing if it would
save others time.
Ah apologies, I was under the impression that you confirmed that this
was already the right fix. It is pretty close to what you describe, so
if you can additionally confirm the fix, that would be great.

Regards,
Salvatore
