Authorship and SOB can't be changed freely, the original must be retained,
because this gives proper credit to the company that sponsored the work.

I.e. if your mail used to be jacob2.chen at rock-chips.com, then I think
we can use that. And if cc at rock-chips.com is a different engineer,
also named Jacob Chen, perhaps we can mention that somewhere to reduce the
confusion.

Thanks,
Ezequiel
