Will add it. Then, the commit log should be: PCI: Add Alibaba Vendor ID to linux/pci_ids.h The Alibaba Vendor ID (0x1ded) is now only used by Alibaba elasticRDMA adapter driver. Move the Vendor ID to linux/pci_ids.h so that it can shared by several drivers later. > > Thanks for sorting the entry correctly! Aha, you are welcome :) Thank you for valuable comments.

We only want to merge things that are needed *now*, i.e., when this complete series is merged. In this case, I think it will be used by another driver that is part of this series ("dwc_pcie_pmu"), so the commit log should mention both Alibaba elasticRDMA ("erdma"?) and "dwc_pcie_pmu". Bjorn

Actually, I mentioned both Alibaba elasticRDMA ("erdma") and PCIe PMU "dwc_pcie_pmu" in initial draft. But I realized that dwc_pcie_pmu is still in review, so I dropped it finally. :( Anyway, I will add it back. Hope you are happy the bellow changes: PCI: Add Alibaba Vendor ID to linux/pci_ids.h The Alibaba Vendor ID (0x1ded) is now used by Alibaba elasticRDMA ("erdma") and will be shared with the upcoming PCIe PMU ("dwc_pcie_pmu"). Move the Vendor ID to linux/pci_ids.h so that it can shared by several drivers later. Thank you. Best Regards, Shuai
