From: Julia Lawall <Julia.Lawall@xxxxxxx> Initialize return variable before exiting on an error path. 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.Lawall@xxxxxxx> --- Actually, orion_spi_reset currently always returns 0, so the test is never true. Perhaps this should be taken into account in some other way. drivers/spi/spi-orion.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/drivers/spi/spi-orion.c b/drivers/spi/spi-orion.c index b17c09c..cc12803 100644 --- a/drivers/spi/spi-orion.c +++ b/drivers/spi/spi-orion.c @@ -435,7 +435,8 @@ static int __init orion_spi_probe(struct platform_device *pdev) } spi->base = ioremap(r->start, SZ_1K); - if (orion_spi_reset(spi) < 0) + status = orion_spi_reset(spi); + if (status < 0) goto out_rel_mem; master->dev.of_node = pdev->dev.of_node; -- To unsubscribe from this list: send the line "unsubscribe kernel-janitors" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
