You need to squash the two commits into a single (and force-push your branch), so you only have a single commit with correctly formatted commit message and correct tab/indentation usage.

In the future I also recommend you create a git branch in your own repository fork to work in, instead of submitting a PR from your master branch. (You don't need to do anything about that at this time, but if you want to submit more pull requests you need to have a separate branch for each.)

@nielsmh Thanks for the info.

Well for this time the changes I made are minor stuffs so I didn't brother to create a new branch. Will do next time if I made any more changes.
