Hi Colin,

The chained GPIO IRQ handler on Tegra calls ->irq_ack on the parent
chip prior to handling the interrupt.

This patch updates the code to use ->irq_eoi now that the GIC has moved
to using the fasteoi flow model.

Thanks Colin.

Works with chained gpio handlers on Tegra, although the patch is
filled with = escaping.

Hmm, I've seen this problem before. See Russell's explanation here:

http://lists.arm.linux.org.uk/lurker/message/20101201.172105.938cf2c5.en.html

I don't believe it's a problem my end, but if it starts happening
regularly I'll investigate further.

Cheers,

Will
