?!?

What happened here? Why are you amending tags?!? That's not allowed. You
cannot change received tags, change people names or their data! And how
is it even possible, srsly, how do you even work with git? Git would
never do it, so you had to do it on purpose via some weird workflow.

Best regards,
Krzysztof

Or should I still keep Krzysztof Kozlowski <krzk+dt@kernel.org>?

Here is the tag you received. You added it in v12.

Why did you change the tag suddenly to something else?

Do you understand that you are not allowed to change people tags? I have
doubts if you ask about people's identities, which is entirely irrelevant.

Best regards,
Krzysztof

I don't know how to say this simpler that you are not allowed to change
tags.

You receive tag, use b4 to apply it or add it manually. Do not alter it.
Do not change it. Do not add things there. Do not remove parts of it.

Tag is as is. You only copy and paste.

Is this understood now?

Fix your workflow and go back to previous version which had correct tag.
And answer - why did you decide to change it?

Best regards,
Krzysztof

Sorry, I understand the tag means now.
It should keep original review-by tag. And send v14.
