I'm carrying an identical patch (though without the reordering) from Luca Weiss.
I thought as the whole series was very late in the cycle that it was unlikely
to be necessary to rush this in.

https://lore.kernel.org/all/20230414-pmi632-v1-5-fe94dc414832@xxxxxxxxx/

I see that patch is for the fairphone-fp3 adn this report is the fairphone-fp4.
Is that the reason this is a fix?

I'm also I'd like someone from driver side to confirm the drier supports this.
