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 Signed-off-by: Greg Kroah-Hartman --- diff --git a/drivers/usb/host/ehci-spear.c b/drivers/usb/host/ehci-spear.c index 466c1bb5b967..210bb676f22f 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);
