From f3b77727e82722fafb1940b3fc15bfdddd9aab4a Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Sun, 29 Dec 2013 23:47:23 +0100 Subject: drivers/dma: fix error return code Set the return variable to an error code as done elsewhere in the function. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // ( if@p1 (\(ret < 0\|ret != 0\)) { ... return ret; } | ret@p1 = 0 ) ... when != ret = e1 when != &ret *if(...) { ... when != ret = e2 when forall return ret; } // Signed-off-by: Julia Lawall Signed-off-by: Vinod Koul --- drivers/dma/ppc4xx/adma.c | 1 + 1 file changed, 1 insertion(+) (limited to 'drivers/dma/ppc4xx/adma.c') diff --git a/drivers/dma/ppc4xx/adma.c b/drivers/dma/ppc4xx/adma.c index 8da48c6b2a38..f9e5c0a5e494 100644 --- a/drivers/dma/ppc4xx/adma.c +++ b/drivers/dma/ppc4xx/adma.c @@ -4139,6 +4139,7 @@ static int ppc440spe_adma_probe(struct platform_device *ofdev) regs = ioremap(res.start, resource_size(&res)); if (!regs) { dev_err(&ofdev->dev, "failed to ioremap regs!\n"); + ret = -ENOMEM; goto err_regs_alloc; } -- cgit v1.2.3
