In the case of omap-dmic.c, the error-handling code of devm_ioremap_resource is also corrected to include releasing the clock. A simplified version of the semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // @@ expression pdev,res,e,e1; expression ret != 0; identifier l; @@ res = platform_get_resource_byname(...); - if (res == NULL) { ... \(goto l;\|return ret;\) } e = devm_ioremap_resource(e1, res); // Signed-off-by: Julia Lawall Acked-by: Jarkko Nikula --- sound/soc/omap/omap-dmic.c | 9 +++------ sound/soc/omap/omap-mcpdm.c | 3 --- 2 files changed, 3 insertions(+), 9 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html diff --git a/sound/soc/omap/omap-dmic.c b/sound/soc/omap/omap-dmic.c index 4db1f8e..12e566b 100644 --- a/sound/soc/omap/omap-dmic.c +++ b/sound/soc/omap/omap-dmic.c @@ -480,15 +480,12 @@ static int asoc_dmic_probe(struct platform_device *pdev) dmic->dma_data.filter_data = "up_link"; res = platform_get_resource_byname(pdev, IORESOURCE_MEM, "mpu"); - if (!res) { - dev_err(dmic->dev, "invalid memory resource\n"); - ret = -ENODEV; + dmic->io_base = devm_ioremap_resource(&pdev->dev, res); + if (IS_ERR(dmic->io_base)) { + ret = PTR_ERR(dmic->io_base); goto err_put_clk; } - dmic->io_base = devm_ioremap_resource(&pdev->dev, res); - if (IS_ERR(dmic->io_base)) - return PTR_ERR(dmic->io_base); ret = snd_soc_register_component(&pdev->dev, &omap_dmic_component, &omap_dmic_dai, 1); diff --git a/sound/soc/omap/omap-mcpdm.c b/sound/soc/omap/omap-mcpdm.c index a49dc52..90d2a7c 100644 --- a/sound/soc/omap/omap-mcpdm.c +++ b/sound/soc/omap/omap-mcpdm.c @@ -480,9 +480,6 @@ static int asoc_mcpdm_probe(struct platform_device *pdev) mcpdm->dma_data[1].filter_data = "up_link"; res = platform_get_resource_byname(pdev, IORESOURCE_MEM, "mpu"); - if (res == NULL) - return -ENOMEM; - mcpdm->io_base = devm_ioremap_resource(&pdev->dev, res); if (IS_ERR(mcpdm->io_base)) return PTR_ERR(mcpdm->io_base);
