I'm thinking that could we solve this so that we call
acpi_gpiochip_request_interrupts() at the end of gpiochip_irqchip_add()
and convert both pinctrl-baytrail and gpio-lynxpoint to use
gpiochip_irqchip_add()?

Yes that seems like a great way to solve it actually.

Is someone able to do this refactoring?

I have both Haswell and Baytrail hardware here so I can take a look if I
have time.

I don't know if you have a case of an ACPI-based GPIO controller
that is *not* supplying interrupts? Because in that case this
would even be required for the thing to work, right?

Both Haswell and Baytrail support interrupts but only the later provides
ACPI events as far as I can tell.
