The current code doesn't check if GPIOLIB_IRQCHIP is enabled, which results in
a compilation error when trying to build gpio-regmap if CONFIG_GPIOLIB_IRQCHIP
isn't enabled.

Fixes: 6a45b0e2589f ("gpiolib: Introduce gpiochip_irqchip_add_domain()")

I suppose this will go through the pinctrl tree.

Yups I applied them.

To make things mess-resistant I have applied them on an
immutable branch and then merged that to devel:
https://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl.git/log/?h=ib-bcm63xx

If we get problems between GPIO and pin control you can
pull this in, but let's hope not!

Yours,
Linus Walleij
