Hi William, here is somebody talking to you.

This part of the code was exactly what you wrote, with no change.

http://patchwork.ozlabs.org/patch/40126/

Are you telling us somebody else added bug to your code ?
This is not the case, obviously.

After bug fix and cleanup code looks good, and even checkpatch.pl is
fine with it. No need for useless brackets around "return XXX;"
If I remember well, I did the cleanup so that my patch could not trigger
checkpatch.pl errors/warnings. Not that I am a particular checkpatch
fan, but I know some people are.

By the way, you were CCed when I sent one month ago the mail to
David/netdev. And no reaction from you at that time.
