If anyone has any objections, please let me know. ------------------ From: David Cohen commit 01bb59ebffdec314da8da66266edf29529372f9b upstream. 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 --- drivers/usb/host/xhci.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) --- a/drivers/usb/host/xhci.c +++ b/drivers/usb/host/xhci.c @@ -404,16 +404,16 @@ static int xhci_try_enable_msi(struct us #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) { }
