Thank you for your contribution.
We're generally pretty strict about the coding style for new code; it
can be found at Documentation/development/coding-style-policy.md in the
source tree. If you don't see what the problem is, pay particular
attention to spacing around parentheses, and to the placement of braces
{}. I'd normally just fix this myself on such a small patch, but since
Wayne has taken this thread I'll let him wait for you to submit a fixed
patch. Just thought I'd explain in a bit more detail.
