From e56faff57f0b39661093c00e0262d4ab9088830e Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas Date: Fri, 28 Feb 2020 15:02:03 -0600 Subject: PCI: Add pci_speed_string() Add pci_speed_string() to return a text description of the supplied bus or link speed. The slot code previously used the private pci_bus_speed_strings[] array for this purpose, but adding this interface will enable us to consolidate similar code elsewhere. Export pcie_link_speed[] and pci_speed_string() so they can be used by modules.
