From 9aebc962767194c330868f53e293d4179919912c Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Wed, 14 Aug 2013 11:11:14 +0200 Subject: watchdog: nuc900_wdt.c: simplify use of devm_ioremap_resource 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/) // @@ 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); // Signed-off-by: Julia Lawall Reviewed-by: Guenter Roeck Acked-by: Wan Zongshun Signed-off-by: Wim Van Sebroeck --- drivers/watchdog/nuc900_wdt.c | 5 ----- 1 file changed, 5 deletions(-) (limited to 'drivers/watchdog') diff --git a/drivers/watchdog/nuc900_wdt.c b/drivers/watchdog/nuc900_wdt.c index e2b6d2cf5c9d..b15b6efd91a1 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); -- cgit v1.2.3-70-g09d2
