Thanks for the patch.
So Ruyi sent the exact same one earlier this year already:
https://lore.kernel.org/linux-arm-kernel/20220408094817.2494756-1-lv.ruyi@xxxxxxxxxx/

I asked Arnd and Olof to take it back then (see my reply), but this somehow
got lost.

I will try to push on both Ruyi's and your second patch again - but I
guess only after the holidays.

Cheers,
Andre
