From e044253b3b4fb5a8b275202511a4d9765ac0a982 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Wed, 14 Aug 2013 11:11:21 +0200 Subject: rtc: 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. 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/) // @@ 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 [viresh.kumar@linaro.org: acked rtc-spear] Acked-by: Viresh Kumar Signed-off-by: Alexandre Belloni --- drivers/rtc/rtc-spear.c | 7 +------ 1 file changed, 1 insertion(+), 6 deletions(-) (limited to 'drivers/rtc/rtc-spear.c') diff --git a/drivers/rtc/rtc-spear.c b/drivers/rtc/rtc-spear.c index d2cdb9823a15..f05ef8568480 100644 --- a/drivers/rtc/rtc-spear.c +++ b/drivers/rtc/rtc-spear.c @@ -358,12 +358,6 @@ static int spear_rtc_probe(struct platform_device *pdev) int status = 0; int irq; - res = platform_get_resource(pdev, IORESOURCE_MEM, 0); - if (!res) { - dev_err(&pdev->dev, "no resource defined\n"); - return -EBUSY; - } - config = devm_kzalloc(&pdev->dev, sizeof(*config), GFP_KERNEL); if (!config) return -ENOMEM; @@ -383,6 +377,7 @@ static int spear_rtc_probe(struct platform_device *pdev) return status; } + res = platform_get_resource(pdev, IORESOURCE_MEM, 0); config->ioaddr = devm_ioremap_resource(&pdev->dev, res); if (IS_ERR(config->ioaddr)) return PTR_ERR(config->ioaddr); -- cgit
