Add CONFIG_PM_SLEEP to suspend/resume functions to fix the following build warning when CONFIG_PM_SLEEP is not selected. This is because sleep PM callbacks defined by SIMPLE_DEV_PM_OPS are only used when the CONFIG_PM_SLEEP is enabled. drivers/usb/host/ehci-spear.c:82:12: warning: 'ehci_spear_drv_suspend' defined but not used [-Wunused-function] drivers/usb/host/ehci-spear.c:90:12: warning: 'ehci_spear_drv_resume' defined but not used [-Wunused-function] Signed-off-by: Jingoo Han <jg1.han@xxxxxxxxxxx> --- drivers/usb/host/ehci-spear.c | 4 ++-- 1 files changed, 2 insertions(+), 2 deletions(-) diff --git a/drivers/usb/host/ehci-spear.c b/drivers/usb/host/ehci-spear.c index 466c1bb..210bb67 100644 --- a/drivers/usb/host/ehci-spear.c +++ b/drivers/usb/host/ehci-spear.c @@ -78,7 +78,7 @@ static const struct hc_driver ehci_spear_hc_driver = { .clear_tt_buffer_complete = ehci_clear_tt_buffer_complete, }; -#ifdef CONFIG_PM +#ifdef CONFIG_PM_SLEEP static int ehci_spear_drv_suspend(struct device *dev) { struct usb_hcd *hcd = dev_get_drvdata(dev); @@ -94,7 +94,7 @@ static int ehci_spear_drv_resume(struct device *dev) ehci_resume(hcd, false); return 0; } -#endif /* CONFIG_PM */ +#endif /* CONFIG_PM_SLEEP */ static SIMPLE_DEV_PM_OPS(ehci_spear_pm_ops, ehci_spear_drv_suspend, ehci_spear_drv_resume); -- 1.7.2.5 -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
