When renesas module is not built, we get compiler warning on xhci driver with W=1 CC [M] drivers/usb/host/xhci-rcar.o drivers/usb/host/xhci-pci.h:13:5: warning: no previous prototype for ‘renesas_xhci_check_request_fw’ [-Wmissing-prototypes] int renesas_xhci_check_request_fw(struct pci_dev *dev, ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~ drivers/usb/host/xhci-pci.h:19:6: warning: no previous prototype for ‘renesas_xhci_pci_exit’ [-Wmissing-prototypes] void renesas_xhci_pci_exit(struct pci_dev *dev) { }; ^~~~~~~~~~~~~~~~~~~~~ We have defined these symbols when CONFIG_USB_XHCI_PCI_RENESAS is not defined, but missed making then static.
