Many thx for taking care of this.

Do you plan to send this to Linus before he releases the final? Or
should I point him to this patch (or a later version) in my weekly
report so that he can decide himself if he wants to pick it up?

There is afaics also one small thing to improve, please add the
following tags to make things easier for future code archaeologists:

Reported-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>
Link:
https://lore.kernel.org/all/f591b13c-4600-e2a4-8efa-aac6ad828dd1@linaro.org/

To explain: Linus[1] and others considered proper link tags with the URL
to the report important, as they allow anyone to look into the backstory
of a fix weeks or years later. That's nothing new, the documentation[2]
for some time says to place such tags in cases like this. I care
personally (and made it a bit more explicit in the docs a while ago),
because these tags make my regression tracking efforts a whole lot
easier, as they allow my tracking bot 'regzbot' to automatically connect
reports with patches posted or committed to fix tracked regressions.

Apropos regzbot, let me tell regzbot to monitor this thread:

#regzbot ^backmonitor:
