Did you find this copy and paste bug by testing or reviewing the code?
How does this bug look like to a user?  Please put that in your commit
message.

This looks reasonable to me, but the patch is badly formatted.

1) It should say [PATCH] in the subject.
2) The body of the email should be the commit message.
3) the --- should only come after the Signed-off-by line.

Try applying your patch with `git am` and review the log to see what I
mean.
