From 152b861622d55f7b17cb6069bd0b275fb559c29a Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Thu, 12 Jan 2012 10:55:05 +0100 Subject: mtd: onenand: samsung: add missing iounmap Add missing iounmap in error handling code, in a case where the function already preforms iounmap on some other execution path. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // @@ expression e; statement S,S1; int ret; @@ e = \(ioremap\|ioremap_nocache\)(...) ... when != iounmap(e) if (<+...e...+>) S ... when any when != iounmap(e) *if (...) { ... when != iounmap(e) return ...; } ... when any iounmap(e); // Signed-off-by: Julia Lawall Signed-off-by: Artem Bityutskiy Signed-off-by: David Woodhouse --- drivers/mtd/onenand/samsung.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'drivers/mtd/onenand') diff --git a/drivers/mtd/onenand/samsung.c b/drivers/mtd/onenand/samsung.c index fa1ee43f735..deaf7628773 100644 --- a/drivers/mtd/onenand/samsung.c +++ b/drivers/mtd/onenand/samsung.c @@ -923,7 +923,7 @@ static int s3c_onenand_probe(struct platform_device *pdev) r = platform_get_resource(pdev, IORESOURCE_MEM, 1); if (!r) { dev_err(&pdev->dev, "no buffer memory resource defined\n"); - return -ENOENT; + err = -ENOENT; goto ahb_resource_failed; } @@ -964,7 +964,7 @@ static int s3c_onenand_probe(struct platform_device *pdev) r = platform_get_resource(pdev, IORESOURCE_MEM, 1); if (!r) { dev_err(&pdev->dev, "no dma memory resource defined\n"); - return -ENOENT; + err = -ENOENT; goto dma_resource_failed; } -- cgit v1.2.3
