The order here doesn't look right. As the sender, your sign-off should
be last. Is Jianxin the author or are you? If Jianxin, there should be
a "From:" line at the beginning of the changelog to indicate authorship
that's different from the sender.

minor nit: can you use comments/whitespace here to indicate holes?
Please see the other amlogic files in this dir for examples.
