I thought maybe it got assigned to Lorenzo because it touches drivers/pci/controller/, but I can't find it in patchwork (https://patchwork.kernel.org/project/linux-pci/list/) at all. Would you mind posting it again to make sure patchwork picks it up? If it's not in patchwork, it's very likely to get missed.
