Hey Tzung-Bi, it looks like you've already created a tag for the
v6.2 pull request, so I don't know if it's too late to apply this
for the current dev cycle.
So, I've not applied it, but have left the Acked-by tag.

Please feel free to apply it if there's still room for it before
you send out the pull request.

Thanks!
