Why? The required dependencies are only in 5,19, and are
definitely NOT a stable candidate...

This isn't a fix by any stretch of the imagination.


Hi Marc,

While I didn't mark it for stable (and it shouldn't go into any branch
earlier than 5.19.x), I did send the patches making the irqchips
immutable to Linus Torvalds as fixes as they technically do *fix* the
warning emitted by gpiolib and make the implementation correct.

I think these patches should still be part of the v5.19.x stable branch.

Yes, and as far as I see we are taking those fixes too.
