Ah, interesting. I checked and as far as I could tell Richard had
manually added the tag when sending v2, so I didn't assume it as a
tool-added tag. I'm happy to let "b4" be the canonical thing that says
what the order should be.

OK, so I just tried this and I'm confused. I ran:

b4 am -P_ 20230201-innolux-g070ace-v2-2-2371e251dd40@...data.com

...and when I check the patch that b4 spits out my "Reviewed-by" tag
is _after_ the "Signed-off-by" tag, just like I asked for.

Just in case Acked-by was somehow different than Reviewed-by, I went
back to the original version where you added the Acked-by:

 b4 am -P_ 20221118075856.401373-1-richard.leitner@...ux.dev

...and, again, it matches the order that I thought was right. In other
words, the patch file generated says:

> Signed-off-by: Richard Leitner <richard.leitner@...data.com>
> Acked-by: Krzysztof Kozlowski <krzysztof.kozlowski@...aro.org>

My "b4" is from Dec 1 of last year, so maybe something changed? Let's
update! OK, I synced b4 and now I'm at v0.12.2 from Match 10 (MARIO
day!). The behavior is unchanged.

Did I get something wrong in the above?
