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.

Jason might not like this. He submitted a patch a few days ago
removing all blinking LEDs.
