From de75577c8c3ab733f808c65e1a9d55882efde68e Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Sat, 20 Aug 2011 08:12:41 +0200 Subject: [PATCH] ALSA: sound/aoa/fabrics/layout.c: remove unneeded kfree The label outnodev is only used when kzalloc has not yet taken place or has failed, so there is no need for the call for kfree under this label. 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 Signed-off-by: Takashi Iwai --- sound/aoa/fabrics/layout.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/sound/aoa/fabrics/layout.c b/sound/aoa/fabrics/layout.c index 3fd1a7e24928..552b97afbca5 100644 --- a/sound/aoa/fabrics/layout.c +++ b/sound/aoa/fabrics/layout.c @@ -1073,10 +1073,10 @@ static int aoa_fabric_layout_probe(struct soundbus_dev *sdev) sdev->pcmid = -1; list_del(&ldev->list); layouts_list_items--; + kfree(ldev); outnodev: of_node_put(sound); layout_device = NULL; - kfree(ldev); return -ENODEV; } -- 2.20.1
