From: Julia Lawall <[email protected]> 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 <[email protected]> --- drivers/spi/spi-ep93xx.c | 1 + 1 file changed, 1 insertion(+) diff --git a/drivers/spi/spi-ep93xx.c b/drivers/spi/spi-ep93xx.c index f97f1d2..9e7fdfd 100644 --- a/drivers/spi/spi-ep93xx.c +++ b/drivers/spi/spi-ep93xx.c @@ -1105,6 +1105,7 @@ static int __devinit ep93xx_spi_probe(struct platform_device *pdev) espi->wq = create_singlethread_workqueue("ep93xx_spid"); if (!espi->wq) { dev_err(&pdev->dev, "unable to create workqueue\n"); + error = -ENOMEM; goto fail_free_dma; } INIT_WORK(&espi->msg_work, ep93xx_spi_work); -- 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/
