Many thx for taking care of this!

Sigh. FWIW, I think that should have gone straight to mainline, as the
situation afaics is quite similar to this one where Linus clarified that
he wants such fixes even at this stage of the cycle:

https://lore.kernel.org/all/CAHk-=wis_qQy4oDNynNKi5b7Qhosmxtoj1jxo5wmB6SRUwQUBQ@xxxxxxxxxxxxxx/

Given that this is a hardware that likely is not much in use any more I
guess it's not making much noise about besides this mail.

Alf: that patch lacks a stable tag, so there is no guarantee that the
fix will be backported to 6.12.y and earlier; but it likely will due to
the Fixes tag. If it wasn't backported within 2 weeks after 6.13-rc1 is
out, please speak up.

Ciao, Thorsten
