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]
It happens due to lack of __maybe_unused flag on xhci_msix_sync_irqs() function in case of !CONFIG_PCI. Signed-off-by: David Cohen <[email protected]> --- Change v1 -> v2: - xhci_msix_sync_irqs() already uses __maybe_unused flag when CONFIG_PCI is set. Proper solution is to add same flag when !CONFIG_PCI instead of define function as inline. drivers/usb/host/xhci.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/usb/host/xhci.c b/drivers/usb/host/xhci.c index 4265b48856f6..ed6b717b8ee1 100644 --- a/drivers/usb/host/xhci.c +++ b/drivers/usb/host/xhci.c @@ -406,7 +406,7 @@ static void xhci_cleanup_msix(struct xhci_hcd *xhci) { } -static void xhci_msix_sync_irqs(struct xhci_hcd *xhci) +static void __maybe_unused xhci_msix_sync_irqs(struct xhci_hcd *xhci) { } -- 1.8.4.2 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
