be removed.

Never send out patches that you do not test-build yourself. Breaking
the build is a quick way to make a maintainer grumpy :(

Hi,
This is the friendly patch-bot of Greg Kroah-Hartman. You have sent him
a patch that has triggered this response. He used to manually respond
to these common problems, but in order to save his sanity (he kept
writing the same thing over and over, yet to different people), I was
created. Hopefully you will not take offence and will fix the problem
in your patch and resubmit it so that it can be accepted into the Linux
kernel tree.
You are receiving this message because of the following common error(s)
as indicated below:
- It looks like you did not use your "real" name for the patch on either
the Signed-off-by: line, or the From: line (both of which have to
match). Please read the kernel file, Documentation/SubmittingPatches
for how to do this correctly.
If you wish to discuss this problem further, or you have questions about
how to resolve this issue, please feel free to respond to this email and
Greg will reply once he has dug out from the pending patches received
from other developers.
thanks,
greg k-h's patch email bot
