This is because sleep PM callbacks defined by SIMPLE_DEV_PM_OPS are only used when the CONFIG_PM_SLEEP is enabled. drivers/block/nvme-core.c:2541:12: warning: 'nvme_suspend' defined but not used [-Wunused-function] drivers/block/nvme-core.c:2550:12: warning: 'nvme_resume' defined but not used [-Wunused-function] Signed-off-by: Jingoo Han Signed-off-by: Matthew Wilcox --- diff --git a/drivers/block/nvme-core.c b/drivers/block/nvme-core.c index 51824d1f23ea..87dd4c79e65f 100644 --- a/drivers/block/nvme-core.c +++ b/drivers/block/nvme-core.c @@ -2538,6 +2538,7 @@ static void nvme_remove(struct pci_dev *pdev) #define nvme_slot_reset NULL #define nvme_error_resume NULL +#ifdef CONFIG_PM_SLEEP static int nvme_suspend(struct device *dev) { struct pci_dev *pdev = to_pci_dev(dev); @@ -2558,6 +2559,7 @@ static int nvme_resume(struct device *dev) } return 0; } +#endif static SIMPLE_DEV_PM_OPS(nvme_dev_pm_ops, nvme_suspend, nvme_resume);
