Hello all:
After communicated with my company, I am permitted to use my company
email to send patches to open source community.
My company supports what I have done for open source community, but at
present, I still use my personal mail id as Signed-of-by (make and send
patches mainly during my free time).
And thank my company for the support.
Thanks.
