This patch looks correct. I'm just running it through our Jenkins to 
sanity check it. A few minor issues.

1. I'd like to omit the whitespace modifications so it's clear that it's 
just the 2 lines that were added for this change.

2. Our project uses "Signed-off-by" as an indication of code review. 
While we are aware this is contrary to how most git projects work, this 
is the current situation. For consistency, I would remove your signoff 
and add my own to indicate I reviewed the patch before pushing to 
master. Does that sound okay?
