From a063158b20afea3cf0dfebea4a17c4e985fb6017 Mon Sep 17 00:00:00 2001 From: David Heidelberg Date: Sun, 6 Feb 2022 21:29:45 +0100 Subject: [PATCH] iommu/msm: Simplify with dev_err_probe() Use the dev_err_probe() helper to simplify error handling during probe. This also handle scenario, when EDEFER is returned and useless error is printed. Fixes warnings as: msm_iommu 7500000.iommu: could not get smmu_pclk Signed-off-by: David Heidelberg Link: https://lore.kernel.org/r/20220206202945.465195-1-david@ixit.cz Signed-off-by: Joerg Roedel --- drivers/iommu/msm_iommu.c | 24 ++++++++++-------------- 1 file changed, 10 insertions(+), 14 deletions(-) diff --git a/drivers/iommu/msm_iommu.c b/drivers/iommu/msm_iommu.c index 06bde6b..e98de16 100644 --- a/drivers/iommu/msm_iommu.c +++ b/drivers/iommu/msm_iommu.c @@ -710,36 +710,32 @@ static int msm_iommu_probe(struct platform_device *pdev) INIT_LIST_HEAD(&iommu->ctx_list); iommu->pclk = devm_clk_get(iommu->dev, "smmu_pclk"); - if (IS_ERR(iommu->pclk)) { - dev_err(iommu->dev, "could not get smmu_pclk\n"); - return PTR_ERR(iommu->pclk); - } + if (IS_ERR(iommu->pclk)) + return dev_err_probe(iommu->dev, PTR_ERR(iommu->pclk), + "could not get smmu_pclk\n"); ret = clk_prepare(iommu->pclk); - if (ret) { - dev_err(iommu->dev, "could not prepare smmu_pclk\n"); - return ret; - } + if (ret) + return dev_err_probe(iommu->dev, ret, + "could not prepare smmu_pclk\n"); iommu->clk = devm_clk_get(iommu->dev, "iommu_clk"); if (IS_ERR(iommu->clk)) { - dev_err(iommu->dev, "could not get iommu_clk\n"); clk_unprepare(iommu->pclk); - return PTR_ERR(iommu->clk); + return dev_err_probe(iommu->dev, PTR_ERR(iommu->clk), + "could not get iommu_clk\n"); } ret = clk_prepare(iommu->clk); if (ret) { - dev_err(iommu->dev, "could not prepare iommu_clk\n"); clk_unprepare(iommu->pclk); - return ret; + return dev_err_probe(iommu->dev, ret, "could not prepare iommu_clk\n"); } r = platform_get_resource(pdev, IORESOURCE_MEM, 0); iommu->base = devm_ioremap_resource(iommu->dev, r); if (IS_ERR(iommu->base)) { - dev_err(iommu->dev, "could not get iommu base\n"); - ret = PTR_ERR(iommu->base); + ret = dev_err_probe(iommu->dev, PTR_ERR(iommu->base), "could not get iommu base\n"); goto fail; } ioaddr = r->start; -- 2.7.4
