It is tempting to squash all clean ups in one patch but every patch has to be *logically* split so that it contains one logical change. I will comment on it. You will need to split patch (4) and repost it, but first trim the CC list, do not copy any maintainer other than pci/dwc ones on the series resulting from patch (4) rework. If there is anything unclear please do let me know. Thanks, Lorenzo
