From b7d12a8667d78ba340829280da8ff62d3b733664 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Wed, 14 Aug 2013 11:11:27 +0200 Subject: [PATCH] drivers/i2c/busses/i2c-ocores.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. 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 Signed-off-by: Wolfram Sang --- drivers/i2c/busses/i2c-ocores.c | 5 +---- 1 file changed, 1 insertion(+), 4 deletions(-) diff --git a/drivers/i2c/busses/i2c-ocores.c b/drivers/i2c/busses/i2c-ocores.c index bdae4ca..7ac8b9c 100644 --- a/drivers/i2c/busses/i2c-ocores.c +++ b/drivers/i2c/busses/i2c-ocores.c @@ -353,10 +353,6 @@ static int ocores_i2c_probe(struct platform_device *pdev) int ret; int i; - res = platform_get_resource(pdev, IORESOURCE_MEM, 0); - if (!res) - return -ENODEV; - irq = platform_get_irq(pdev, 0); if (irq < 0) return irq; @@ -365,6 +361,7 @@ static int ocores_i2c_probe(struct platform_device *pdev) if (!i2c) return -ENOMEM; + res = platform_get_resource(pdev, IORESOURCE_MEM, 0); i2c->base = devm_ioremap_resource(&pdev->dev, res); if (IS_ERR(i2c->base)) return PTR_ERR(i2c->base); -- 2.7.4
