This is because sleep PM callbacks defined by SIMPLE_DEV_PM_OPS are only used when the CONFIG_PM_SLEEP is enabled. drivers/mmc/host/atmel-mci.c:2509:12: warning: 'atmci_suspend' defined but not used [-Wunused-function] drivers/mmc/host/atmel-mci.c:2539:12: warning: 'atmci_resume' defined but not used [-Wunused-function] Signed-off-by: Jingoo Han Acked-by: Ludovic Desroches Signed-off-by: Chris Ball --- diff --git a/drivers/mmc/host/atmel-mci.c b/drivers/mmc/host/atmel-mci.c index aca59d93d5a9..7d8e87ad6d6d 100644 --- a/drivers/mmc/host/atmel-mci.c +++ b/drivers/mmc/host/atmel-mci.c @@ -2504,7 +2504,7 @@ static int __exit atmci_remove(struct platform_device *pdev) return 0; } -#ifdef CONFIG_PM +#ifdef CONFIG_PM_SLEEP static int atmci_suspend(struct device *dev) { struct atmel_mci *host = dev_get_drvdata(dev); @@ -2559,17 +2559,15 @@ static int atmci_resume(struct device *dev) return ret; } -static SIMPLE_DEV_PM_OPS(atmci_pm, atmci_suspend, atmci_resume); -#define ATMCI_PM_OPS (&atmci_pm) -#else -#define ATMCI_PM_OPS NULL #endif +static SIMPLE_DEV_PM_OPS(atmci_pm, atmci_suspend, atmci_resume); + static struct platform_driver atmci_driver = { .remove = __exit_p(atmci_remove), .driver = { .name = "atmel_mci", - .pm = ATMCI_PM_OPS, + .pm = &atmci_pm, .of_match_table = of_match_ptr(atmci_dt_ids), }, };
