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. 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/nuc900_wdt.c | 5 ----- 1 file changed, 5 deletions(-) diff --git a/drivers/watchdog/nuc900_wdt.c b/drivers/watchdog/nuc900_wdt.c index e2b6d2c..b15b6ef 100644 --- a/drivers/watchdog/nuc900_wdt.c +++ b/drivers/watchdog/nuc900_wdt.c @@ -256,11 +256,6 @@ static int nuc900wdt_probe(struct platform_device *pdev) spin_lock_init(&nuc900_wdt->wdt_lock); res = platform_get_resource(pdev, IORESOURCE_MEM, 0); - if (res == NULL) { - dev_err(&pdev->dev, "no memory resource specified\n"); - return -ENOENT; - } - nuc900_wdt->wdt_base = devm_ioremap_resource(&pdev->dev, res); if (IS_ERR(nuc900_wdt->wdt_base)) return PTR_ERR(nuc900_wdt->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
