Hi Linus,

Sorry for the constant spam on this..

Changing the handler to handle_edge_irq() on the gpio side resolves
the issue and gpiomon registers edges from the gpio like it should.
So I think it's an ordering thing. Something like the gpio side sets
the handler to handle_bad_irq() after the irqchip side sets it to
handle_edge_irq().

Thanks for the help.

Cheers,

Daniel
