Signed-off-by has a specific meaning, it typically means someone authored 
or as a maintainer forwarded the code (which did not happen here) - see 
the details in Documentation/SubmittingPatches, under this section:

  12) Sign your work

If Chuansheng found the bug, there's a Reported-by tag. If Chuansheng 
approves of the fix patch then there's Acked-by for that. If he tested it, 
then for that there's the Tested-by tag. You can also add several of those 
tags.

Thanks,
