This is exactly correct. Patch applied.

I tried to hack the sunxi driver to even use the gpiolib
irqchip helpers but exactly this complex map thing in
->irq_array[] git me stuck. If any of you guys could be so
nice to take a stab at this (compare to other commits
converting drivers to use gpiolibs irqchip helpers) then
I'd be very happy.
