It looks like you received a tag and forgot to add it. If you do not know the process, here is a short explanation: Please add Acked-by/Reviewed-by/Tested-by tags when posting new versions, under or above your Signed-off-by tag. Tag is "received", when provided in a message replied to you on the mailing list. Tools like b4 can help here. However, there's no need to repost patches *only* to add the tags. The upstream maintainer will do that for tags received on the version they apply. https://elixir.bootlin.com/linux/v6.5-rc3/source/Documentation/process/submitting-patches.rst#L577 If a tag was not added on purpose, please state why and what changed. Best regards, Krzysztof
