From 3506c0d507144d9b0f19efd5a56d289f70611179 Mon Sep 17 00:00:00 2001 From: Tushar Behera Date: Tue, 6 Dec 2011 16:15:54 +0530 Subject: [PATCH] DMA: PL330: Remove pm_runtime_xxx calls from pl330 probe/remove amba_probe() now calls pm_runtime_get_noresume() and pm_runtime_enable() for the devices before the device probe is called. Hence we don't need to call pm_runtime_get_xxx and pm_runtime_enable() in device probe again. In the same way, since amba_remove() calls the respective pm_runtime functions, those functions need not be called from device remove. This patch fixes following run time error with pl330 driver. dma-pl330 dma-pl330.0: Unbalanced pm_runtime_enable! dma-pl330 dma-pl330.0: failed to get runtime pm Signed-off-by: Giridhar Maruthy Signed-off-by: Tushar Behera Signed-off-by: Vinod Koul --- drivers/dma/pl330.c | 17 ++--------------- 1 file changed, 2 insertions(+), 15 deletions(-) diff --git a/drivers/dma/pl330.c b/drivers/dma/pl330.c index e0da795bdcb3..a5737575d236 100644 --- a/drivers/dma/pl330.c +++ b/drivers/dma/pl330.c @@ -820,17 +820,7 @@ pl330_probe(struct amba_device *adev, const struct amba_id *id) amba_set_drvdata(adev, pdmac); -#ifdef CONFIG_PM_RUNTIME - /* to use the runtime PM helper functions */ - pm_runtime_enable(&adev->dev); - - /* enable the power domain */ - if (pm_runtime_get_sync(&adev->dev)) { - dev_err(&adev->dev, "failed to get runtime pm\n"); - ret = -ENODEV; - goto probe_err1; - } -#else +#ifndef CONFIG_PM_RUNTIME /* enable dma clk */ clk_enable(pdmac->clk); #endif @@ -971,10 +961,7 @@ static int __devexit pl330_remove(struct amba_device *adev) res = &adev->res; release_mem_region(res->start, resource_size(res)); -#ifdef CONFIG_PM_RUNTIME - pm_runtime_put(&adev->dev); - pm_runtime_disable(&adev->dev); -#else +#ifndef CONFIG_PM_RUNTIME clk_disable(pdmac->clk); #endif
