Never really been clear on this myself. A massive amount of other code does include the comma so that's what I followed. And then a massive amount of other code uses the opposite so I could follow that too.. but I work in most of the asus stuff and it looks like that's what is common there so I'll remove the comma.

Many thanks for taking the time to review.
