usb: ehci-atmel: use __maybe_unused to hide pm functions The ehci-atmel driver uses #ifdef to check for CONFIG_PM, but then uses SIMPLE_DEV_PM_OPS, which leaves the references out when CONFIG_PM_SLEEP is not defined, so we get a warning with PM=y && PM_SLEEP=n: drivers/usb/host/ehci-atmel.c:189:12: error: 'ehci_atmel_drv_suspend' defined but not used [-Werror=unused-function] drivers/usb/host/ehci-atmel.c:203:12: error: 'ehci_atmel_drv_resume' defined but not used [-Werror=unused-function] This removes the incorrect #ifdef and instead uses a __maybe_unused annotation to let the compiler know it can silently drop the function definition.
