Please re-send a checkpatch clean version.

Also, the comments on this patch (and the next) are mal-formed.
The commit message must be before the first "---" and the throw-away
comments must be after it, rather thant the reverse.

I ask others to get this right, so it seems most fair that I do the
same for you -- otherwise your next patch will have the same problems
and others will follow your example of not sending the "perfect patch"

thanks,
