It should be disabled by default, so you can skip this.

+ };You can also skip these. The gpio driver will put the pin into gpio mode when the leds/keys driver claims it. It is a case of, i didn't know that, put entries like this into a number of files, and people have been copying my mistake ever since. Thomas made an effort to correct this for some boards.
