pci_host_common_probe() is defined when CONFIG_PCI_HOST_COMMON=y; therefore the function declaration should match that. drivers/pci/host/pcie-tango.c:300:9: error: implicit declaration of function 'pci_host_common_probe' Signed-off-by: Marc Gonzalez <marc_gonzalez@sigmadesigns.com> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
