When CONFIG_PCI and CONFIG_PM are not selected, xhci.c gets this warning: drivers/usb/host/xhci.c:409:13: warning: ‘xhci_msix_sync_irqs’ defined but not used [-Wunused-function] Instead of creating nested #ifdefs, this patch fixes it by defining the xHCI PCI stubs as inline. This warning has been in since 3.2 kernel and was caused by commit 421aa841a134f6a743111cf44d0c6d3b45e3cf8c "usb/xhci: hide MSI code behind PCI bars", but wasn't noticed until 3.13 when a configuration with these options was tried Signed-off-by: David Cohen Signed-off-by: Mathias Nyman Signed-off-by: Greg Kroah-Hartman --- diff --git a/drivers/usb/host/xhci.c b/drivers/usb/host/xhci.c index a90819b83224..4b46de842175 100644 --- a/drivers/usb/host/xhci.c +++ b/drivers/usb/host/xhci.c @@ -394,16 +394,16 @@ static int xhci_try_enable_msi(struct usb_hcd *hcd) #else -static int xhci_try_enable_msi(struct usb_hcd *hcd) +static inline int xhci_try_enable_msi(struct usb_hcd *hcd) { return 0; } -static void xhci_cleanup_msix(struct xhci_hcd *xhci) +static inline void xhci_cleanup_msix(struct xhci_hcd *xhci) { } -static void xhci_msix_sync_irqs(struct xhci_hcd *xhci) +static inline void xhci_msix_sync_irqs(struct xhci_hcd *xhci) { }
