    Hi Donald,
    Since you originally made the patch, can you please confirm that your
    Signed-off-by
    "Signed-off-by: Donald Lee <Donald_Lee@trendmicro.com>"
    can be added into the patch's changelog?
    
    Thanks,
    -- Dexuan


Hi Dexuan, 

Yes! Can you please add my signed-off on it? Our mailing system will add extra space on the patch last time I did. Thank you.

Regards,
Donald
