I assume you didn't find the problem just looking through the code by
hand.  If you used a tool, it would be really good to acknowledge the tool
that was used.  The tools don't come for free, and you don't pay for them.
The only payment that you can offer is to acknowledge that the tool was
used, which helps justify that the tool is useful and what it is useful
for.

Sorry, I forgot edit the commit log and add this info.

It was detected by Coccinelle, I will add this and resend.
