If this is used by a GPIO chip (as happens in another part of
the series), you need to set up the .irq_request_resources()
and .irq_release_resources() to call gpiochip_lock_as_irq()
and gpiochip_unlock_as_irq().
As with the other comment on the GPIO patch, the separation
of concerns between irqchip and gpiochip is a bit artificial
here and breaks down somewhat.
Yours,
Linus Walleij
