That should work too.

I posted a couple patches last Friday to remove irq_to_gpio:

Later in the thread, you said you would merge them into your branch to
avoid merge conflicts with the other GPIO work you were doing.

For gpio_to_irq, yes, I believe we get rid of it pretty easily; we'd
just need to implement gpio-tegra.c's gpio_chip.to_irq function. Should
I cook up a patch based on top of linux-next plus the two patches above
to do that instead?
