Fair enough. I guess the updated message is slightly better:

Acked-by: Kai Huang <kai.huang@xxxxxxxxx>

Btw, I think there are some issues in the patch title/changelog. Please
fix them.

E.g., I think the format of patch title should be:

In the changelog please avoid using "we", and please use imperative mode
to describe the change. More information please see:
