From 0bb98ba2b045e53b4724f34509455b7653c329d3 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Sun, 21 Aug 2011 13:18:45 +0200 Subject: [PATCH] sound/soc/mxs/mxs-saif.c: add missing kfree Move the test on pdev->id before the kzalloc to avoid requiring kfree when the test fails. This fix was suggested by Wolfram Sang. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // @@ identifier x; expression E1!=0,E2,E3,E4; statement S; iterator I; @@ ( if (...) { ... when != kfree(x) when != x = E3 when != E3 = x * return ...; } ... when != x = E2 when != I(...,x,...) S if (...) { ... when != x = E4 kfree(x); ... return ...; } ) // Signed-off-by: Julia Lawall Acked-by: Dong Aisheng Reviewed-by: Wolfram Sang Acked-by: Liam Girdwood Signed-off-by: Mark Brown --- sound/soc/mxs/mxs-saif.c | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) diff --git a/sound/soc/mxs/mxs-saif.c b/sound/soc/mxs/mxs-saif.c index 530017f7d14a..af5734f6dab7 100644 --- a/sound/soc/mxs/mxs-saif.c +++ b/sound/soc/mxs/mxs-saif.c @@ -521,12 +521,13 @@ static int mxs_saif_probe(struct platform_device *pdev) struct mxs_saif *saif; int ret = 0; + if (pdev->id >= ARRAY_SIZE(mxs_saif)) + return -EINVAL; + saif = kzalloc(sizeof(*saif), GFP_KERNEL); if (!saif) return -ENOMEM; - if (pdev->id >= ARRAY_SIZE(mxs_saif)) - return -EINVAL; mxs_saif[pdev->id] = saif; saif->clk = clk_get(&pdev->dev, NULL); -- 2.20.1
