From: Peter Senna Tschudin <[email protected]> Convert a nonnegative error return code to a negative one, as returned 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: Peter Senna Tschudin <[email protected]> --- drivers/net/irda/sh_irda.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/drivers/net/irda/sh_irda.c b/drivers/net/irda/sh_irda.c index eb315b8..4b746d9 100644 --- a/drivers/net/irda/sh_irda.c +++ b/drivers/net/irda/sh_irda.c @@ -808,8 +808,8 @@ static int __devinit sh_irda_probe(struct platform_device *pdev) goto err_mem_4; platform_set_drvdata(pdev, ndev); - - if (request_irq(irq, sh_irda_irq, IRQF_DISABLED, "sh_irda", self)) { + err = request_irq(irq, sh_irda_irq, IRQF_DISABLED, "sh_irda", self); + if (err) { dev_warn(&pdev->dev, "Unable to attach sh_irda interrupt\n"); goto err_mem_4; } -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
