From: Julia Lawall <Julia.Lawall@xxxxxxx> Remove unneeded error handling on the result of a call to platform_get_resource when the value is passed to devm_ioremap_resource. Move the call to platform_get_resource adjacent to the call to devm_ioremap_resource to make the connection between them more clear. A simplified version of the semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression pdev,res,n,e,e1; expression ret != 0; identifier l; @@ - res = platform_get_resource(pdev, IORESOURCE_MEM, n); ... when != res - if (res == NULL) { ... \(goto l;\|return ret;\) } ... when != res + res = platform_get_resource(pdev, IORESOURCE_MEM, n); e = devm_ioremap_resource(e1, res); // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@xxxxxxx> --- drivers/spi/spi-sirf.c | 7 +------ 1 file changed, 1 insertion(+), 6 deletions(-) diff --git a/drivers/spi/spi-sirf.c b/drivers/spi/spi-sirf.c index 62c92c3..546fae2 100644 --- a/drivers/spi/spi-sirf.c +++ b/drivers/spi/spi-sirf.c @@ -588,12 +588,6 @@ static int spi_sirfsoc_probe(struct platform_device *pdev) platform_set_drvdata(pdev, master); sspi = spi_master_get_devdata(master); - mem_res = platform_get_resource(pdev, IORESOURCE_MEM, 0); - if (!mem_res) { - dev_err(&pdev->dev, "Unable to get IO resource\n"); - ret = -ENODEV; - goto free_master; - } master->num_chipselect = num_cs; for (i = 0; i < master->num_chipselect; i++) { @@ -620,6 +614,7 @@ static int spi_sirfsoc_probe(struct platform_device *pdev) } } + mem_res = platform_get_resource(pdev, IORESOURCE_MEM, 0); sspi->base = devm_ioremap_resource(&pdev->dev, mem_res); if (IS_ERR(sspi->base)) { ret = PTR_ERR(sspi->base); -- To unsubscribe from this list: send the line "unsubscribe kernel-janitors" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
