Subject: [PATCH v4 08/10] PCI: Add PCIe suffix when display PCIe slot bus speed
Date: Mon, 17 Feb 2020 19:13:02 +0800 [thread overview]
Message-ID: <1581937984-40353-9-git-send-email-yangyicong@hisilicon.com> (raw)
In-Reply-To: <1581937984-40353-1-git-send-email-yangyicong@hisilicon.com>
"PCIe" suffix of PCIe speed strings in pci_bus_speed_strings[]
is removed in previos patch. Add "PCIe" suffix when display PCIe
