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/video/arcfb.c | 1 + 1 file changed, 1 insertion(+) diff --git a/drivers/video/arcfb.c b/drivers/video/arcfb.c index a1d58e9..4659d5d 100644 --- a/drivers/video/arcfb.c +++ b/drivers/video/arcfb.c @@ -552,6 +552,7 @@ static int __devinit arcfb_probe(struct platform_device *dev) "arcfb", info)) { printk(KERN_INFO "arcfb: Failed req IRQ %d\n", par->irq); + retval = -EBUSY; goto err1; } } -- 1.7.11.4 -- 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/
