This turns the IXP4xx GPIO irqchip into an immutable irqchip, a bit different from the standard template due to being hierarchical.
Tested on the IXP4xx which uses drivers/ata/pata_ixp4xx_cf.c for a rootfs on compact flash with IRQs from this GPIO block to the CF ATA controller.

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.
