Presumably you're talking about the struct hw_interrupt_type and the lack
of an irq_desc[irq].handler? There's some migration helper glue in
include/linux/irq.h that you can use, but you're better off converting
completely. You can at least get it building again by changing to
irq_desc[irq].chip, but you really want a proper irq_chip implementation
to go along with this, rather than munging in the hw_interrupt_type.
You can easily compare before-and-after versions of most of the IRQ
controllers to identify the minimal changes required.
