From af2d3139e19fd7da9a5d300a83812616b2d6694c Mon Sep 17 00:00:00 2001 From: Jingoo Han Date: Mon, 27 Oct 2014 21:36:26 +0900 Subject: [PATCH] dmaengine: k3dma: Add CONFIG_PM_SLEEP to suspend/resume functions 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/dma/k3dma.c:790:12: warning: 'k3_dma_suspend' defined but not used [-Wunused-function] drivers/dma/k3dma.c:806:12: warning: 'k3_dma_resume' defined but not used [-Wunused-function] Signed-off-by: Jingoo Han Acked-by: Zhangfei Gao Signed-off-by: Vinod Koul --- drivers/dma/k3dma.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/drivers/dma/k3dma.c b/drivers/dma/k3dma.c index bd8e5f1e826f..a1de14ab2c51 100644 --- a/drivers/dma/k3dma.c +++ b/drivers/dma/k3dma.c @@ -786,6 +786,7 @@ static int k3_dma_remove(struct platform_device *op) return 0; } +#ifdef CONFIG_PM_SLEEP static int k3_dma_suspend(struct device *dev) { struct k3_dma_dev *d = dev_get_drvdata(dev); @@ -815,6 +816,7 @@ static int k3_dma_resume(struct device *dev) k3_dma_enable_dma(d, true); return 0; } +#endif static SIMPLE_DEV_PM_OPS(k3_dma_pmops, k3_dma_suspend, k3_dma_resume); -- 2.39.5
