From: Julia Lawall <julia@xxxxxxx> Go to existing error handling code at the end of the function that calls clk_put. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r exists@ expression e1,e2; statement S; @@ e1 = clk_get@p1(...); ... when != e1 = e2 when != clk_put(e1) when any if (...) { ... when != clk_put(e1) when != if (...) { ... clk_put(e1) ... } * return@p3 ...; } else S // </smpl> Signed-off-by: Julia Lawall <julia@xxxxxxx> --- drivers/net/davinci_emac.c | 10 ++++++---- 1 file changed, 6 insertions(+), 4 deletions(-) diff --git a/drivers/net/davinci_emac.c b/drivers/net/davinci_emac.c index 29a4f06..dcc4a17 100644 --- a/drivers/net/davinci_emac.c +++ b/drivers/net/davinci_emac.c @@ -1781,8 +1781,8 @@ static int __devinit davinci_emac_probe(struct platform_device *pdev) ndev = alloc_etherdev(sizeof(struct emac_priv)); if (!ndev) { dev_err(&pdev->dev, "error allocating net_device\n"); - clk_put(emac_clk); - return -ENOMEM; + rc = -ENOMEM; + goto free_clk; } platform_set_drvdata(pdev, ndev); @@ -1796,7 +1796,8 @@ static int __devinit davinci_emac_probe(struct platform_device *pdev) pdata = pdev->dev.platform_data; if (!pdata) { dev_err(&pdev->dev, "no platform data\n"); - return -ENODEV; + rc = -ENODEV; + goto probe_quit; } /* MAC addr and PHY mask , RMII enable info from platform_data */ @@ -1929,8 +1930,9 @@ no_dma: iounmap(priv->remap_addr); probe_quit: - clk_put(emac_clk); free_netdev(ndev); +free_clk: + clk_put(emac_clk); return rc; } -- 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
