This makes the code *so* much better so patch applied, naturally.

But...

The most modern way would be to take another step and convert the
driver to GPIOLIB_IRQCHIP by stating

select GPIOLIB_IRQCHIP

here.

If you look at other drivers using GPIOLIB_IRQCHIP on an
i2c expander, say gpio-stmpe.c or gpio-tc3589x.c, you
can get a grip on how that works.

So please follow up with a patch converting the driver to
GPIOLIB_IRQCHIP on top of these patches :) if you
have time.

Yours,
