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/watchdog/s3c2410_wdt.c | 7 +------ 1 file changed, 1 insertion(+), 6 deletions(-) diff --git a/drivers/watchdog/s3c2410_wdt.c b/drivers/watchdog/s3c2410_wdt.c index 6a22cf5..9fbc993 100644 --- a/drivers/watchdog/s3c2410_wdt.c +++ b/drivers/watchdog/s3c2410_wdt.c @@ -325,12 +325,6 @@ static int s3c2410wdt_probe(struct platform_device *pdev) dev = &pdev->dev; wdt_dev = &pdev->dev; - wdt_mem = platform_get_resource(pdev, IORESOURCE_MEM, 0); - if (wdt_mem == NULL) { - dev_err(dev, "no memory resource specified\n"); - return -ENOENT; - } - wdt_irq = platform_get_resource(pdev, IORESOURCE_IRQ, 0); if (wdt_irq == NULL) { dev_err(dev, "no irq resource specified\n"); @@ -339,6 +333,7 @@ static int s3c2410wdt_probe(struct platform_device *pdev) } /* get the memory region for the watchdog timer */ + wdt_mem = platform_get_resource(pdev, IORESOURCE_MEM, 0); wdt_base = devm_ioremap_resource(dev, wdt_mem); if (IS_ERR(wdt_base)) { ret = PTR_ERR(wdt_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
