However, there's no need to repost patches *only* to add the tags. The upstream maintainer will do that for acks received on the version they apply. If a tag was not added on purpose, please state why and what changed.

Oh, this patch has error detected and shown in [1]. Therefore, I fix it and state the change at [2]. Thanks for the explanation and time to review the patch. [1] https://patchwork.kernel.org/project/linux-mediatek/patch/20220107095200.4389-2-roger.lu@mediatek.com/ [2] https://patchwork.kernel.org/project/linux-mediatek/cover/20220127033956.24585-1-roger.lu@mediatek.com/ - Remove unnecessary "maxItems" from nvmem-cells in mtk-svs.yaml.

Since this issue [1] is fixed, could I add your Reviewed-by tags back or just send the next version directly without adding any tags.
