From 8ecc7d2b2207ed9642e3d0140bfaa8c93a6ea47f Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Mon, 19 Aug 2013 10:51:52 +0200 Subject: watchdog: simplify platform_get_resource_byname/devm_ioremap_resource Remove unneeded error handling on the result of a call to platform_get_resource_byname 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,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 Reviewed-by: Guenter Roeck Signed-off-by: Wim Van Sebroeck --- drivers/watchdog/ar7_wdt.c | 5 ----- 1 file changed, 5 deletions(-) (limited to 'drivers/watchdog/ar7_wdt.c') diff --git a/drivers/watchdog/ar7_wdt.c b/drivers/watchdog/ar7_wdt.c index 2f3cc8fb471a..b3709f9cf5be 100644 --- a/drivers/watchdog/ar7_wdt.c +++ b/drivers/watchdog/ar7_wdt.c @@ -280,11 +280,6 @@ static int ar7_wdt_probe(struct platform_device *pdev) ar7_regs_wdt = platform_get_resource_byname(pdev, IORESOURCE_MEM, "regs"); - if (!ar7_regs_wdt) { - pr_err("could not get registers resource\n"); - return -ENODEV; - } - ar7_wdt = devm_ioremap_resource(&pdev->dev, ar7_regs_wdt); if (IS_ERR(ar7_wdt)) return PTR_ERR(ar7_wdt); -- cgit v1.2.3
