This doesn't apply to my tree neither for fixes or devel, can you rebase it?
I'd like to queue it on devel for non-urgent fixes.

Yours,

Sure, I will rebase. The issue was because of Andy's commit
https://lore.kernel.org/all/20220401103604.8705-9-andriy.shevchenko@linux.intel.com/
which was in next but not in your tree.

Including such development branches in next, bypassing maintainer, makes
it difficult for everyone else to develop patches... :(


Best regards,
Krzysztof

I'm about to send PR with my stuff to Linus and Bart, but I have difficulties
right now with the signing tag. I hope I figure out sooner than later.
