If there is nothing more severe with this, I am sure Jason can just squash in the nits.

I think this one is debatable. The documentation is called gpio_keys.txt, and the example uses gpio_keys. I don't mind chaging it in this file, but maybe you can submit a patch changing the example in the documentation?

ACK.

This still needs to be tested on hardware, so there is a good chance of a respin.
