From 01bb59ebffdec314da8da66266edf29529372f9b Mon Sep 17 00:00:00 2001 From: David Cohen Date: Fri, 25 Apr 2014 19:20:16 +0300 Subject: usb/xhci: fix compilation warning when !CONFIG_PCI && !CONFIG_PM MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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 Cc: stable@vger.kernel.org # 3.2 Signed-off-by: Mathias Nyman Signed-off-by: Greg Kroah-Hartman --- drivers/usb/host/xhci.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) (limited to 'drivers') diff --git a/drivers/usb/host/xhci.c b/drivers/usb/host/xhci.c index 988ed5f1cb2c..300836972faa 100644 --- a/drivers/usb/host/xhci.c +++ b/drivers/usb/host/xhci.c @@ -408,16 +408,16 @@ 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) { } -- cgit v1.2.3
