Can you resend this patch, with the proper signed-off-by: line, to me
through email as the file Documentation/SubmittingPatches describes so I
can apply it properly and give you the correct credit for this?
Comment 2 Greg Kroah-Hartman 2008-01-01 23:02:07 UTC
patches need to go through email, not bugzilla, closing out as invalid.
