I got your point, you refer to the 'reviewed-by' and 'acked-by' tag in
this patch.
These are the tags from two reviewers.

https://lore.kernel.org/lkml/174172361378.44650.15345202042780383326.robh@kernel.org/


https://lore.kernel.org/lkml/9dca8772-6bc0-4105-98d7-e4f804b0d637@collabora.com/

And tag from 'Yong.Wu at mediatek.com' should be deleted. He just reviewed
this patch in mtk internal gerrit and did not make it pubilc. So I
delete this tag from the patch. I could ask him to help reply a
'reviewed-by' tag if necessary.
Thanks for all.
