From 7a96541a8e9fe720bec3900679ca514fefd2d516 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Wed, 14 Aug 2013 11:11:08 +0200 Subject: mtd: 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: Artem Bityutskiy Signed-off-by: David Woodhouse --- drivers/mtd/devices/elm.c | 5 ----- 1 file changed, 5 deletions(-) (limited to 'drivers/mtd/devices') diff --git a/drivers/mtd/devices/elm.c b/drivers/mtd/devices/elm.c index 4f683d24de5..d1dd6a33a05 100644 --- a/drivers/mtd/devices/elm.c +++ b/drivers/mtd/devices/elm.c @@ -368,11 +368,6 @@ static int elm_probe(struct platform_device *pdev) } res = platform_get_resource(pdev, IORESOURCE_MEM, 0); - if (!res) { - dev_err(&pdev->dev, "no memory resource defined\n"); - return -ENODEV; - } - info->elm_base = devm_ioremap_resource(&pdev->dev, res); if (IS_ERR(info->elm_base)) return PTR_ERR(info->elm_base); -- cgit v1.2.3-70-g09d2
