From: Julia Lawall <julia.law...@lip6.fr> 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/) // <smpl> ( if@p1 (\(ret < 0\|ret != 0\)) { ... return ret; } | ret@p1 = 0 ) ... when != ret = e1 when != &ret *if(...) { ... when != ret = e2 when forall return ret; } // </smpl> Signed-off-by: Julia Lawall <julia.law...@lip6.fr> --- Not tested. drivers/dma/cppi41.c | 4 +++- drivers/dma/ppc4xx/adma.c | 1 + 2 files changed, 4 insertions(+), 1 deletion(-) diff --git a/drivers/dma/cppi41.c b/drivers/dma/cppi41.c index c29dacf..c18aebf 100644 --- a/drivers/dma/cppi41.c +++ b/drivers/dma/cppi41.c @@ -972,8 +972,10 @@ static int cppi41_dma_probe(struct platform_device *pdev) goto err_chans; irq = irq_of_parse_and_map(dev->of_node, 0); - if (!irq) + if (!irq) { + ret = -EINVAL; goto err_irq; + } cppi_writel(USBSS_IRQ_PD_COMP, cdd->usbss_mem + USBSS_IRQ_ENABLER); diff --git a/drivers/dma/ppc4xx/adma.c b/drivers/dma/ppc4xx/adma.c index 8bba298..ce7a8d7 100644 --- a/drivers/dma/ppc4xx/adma.c +++ b/drivers/dma/ppc4xx/adma.c @@ -4114,6 +4114,7 @@ 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; } -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
