From: Jacob Keller <jacob.e.keller@intel.com> pcie_link_speed and pcix_bus_speed are arrays used by probe.c to correctly convert lnksta register values into the pci_bus_speed enum. These static arrays are useful outside probe for this purpose. This patch makes these defines into const arrays and exposes them with an extern header in linux/include/pci.h Signed-off-by: Jacob Keller <jacob.e.keller@intel.com> Tested-by: Phil Schmitt <redacted> Signed-off-by: Jeff Kirsher <redacted> --- drivers/pci/probe.c | 4 ++-- include/linux/pci.h | 3 +++ 2 files changed, 5 insertions(+), 2 deletions(-)
