This patch causes a regression in mainline:
https://lore.kernel.org/all/20230911171102.cwieugrpthm7ywbm@pengutronix.de/

A fix is heading towards mainline now:
https://lore.kernel.org/all/20230917165328.3403-1-jszhang@kernel.org/

Jisheng Zhang already mentioned this and also mentioned that the change
depends on another commit not yet backported:
https://lore.kernel.org/all/ZQHKiU6SNtq7t1Fi@xhacker/

Something feels wrong here; not sure if it is or if I'm missing something.

Ciao, Thorsten (who only noticed this by chance)
