Hi Teshan,
Thank you for the code changes. While we appreciate it, I'm going to NAK the changes. For this sub-system, we are not going to make style changes or fixes unless it's part of functional code changes or refactor. The reason is to not introduce unnecessary churns to the code that can make fix backports difficult later on. Thanks.

I'm going to give it a quick review on the first item at least.

Why? the original code was the standard way to format these and
there is no explanation of the change in the commit message.
Is it because it's over 80 chars long?  That is guidance only and
if readability is hurt (like here) feel free to go up to 100 chars
before worrying about it.
