From 78ef1b1ea193d1b977864f8c20968fcf4f1dbff4 Mon Sep 17 00:00:00 2001 From: Vinod Koul Date: Tue, 19 May 2020 15:00:02 +0530 Subject: [PATCH] usb: xhci: make symbols static MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit 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.
