If you know the process, you can skip it (please do not feel offended by me posting it here - no bad intentions intended). 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 of patchset, under or above your Signed-off-by tag, unless patch changed significantly (e.g. new properties added to the DT bindings). 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/v6.12-rc3/source/Documentation/process/submitting-patches.rst#L577 </form letter> Best regards, Krzysztof
