From c09f5ca7bdc9a82c5f721bc28c46d65452240cfa Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Sat, 20 Aug 2011 09:02:01 +0200 Subject: [PATCH] sound/soc/fsl/mpc8610_hpcd.c: add missing of_node_put The first change is to add an of_node_put, since codec_np has previously been allocated. The rest of the patch reorganizes the error handling code so the only code executed is that which is needed. 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 != of_node_put(x) when != x = E3 when != E3 = x * return ...; } ... when != x = E2 when != I(...,x,...) S if (...) { ... when != x = E4 of_node_put(x); ... return ...; } ) // Signed-off-by: Julia Lawall Acked-by: Timur Tabi Acked-by: Liam Girdwood Signed-off-by: Mark Brown --- sound/soc/fsl/mpc8610_hpcd.c | 18 +++++++++--------- 1 file changed, 9 insertions(+), 9 deletions(-) diff --git a/sound/soc/fsl/mpc8610_hpcd.c b/sound/soc/fsl/mpc8610_hpcd.c index a192979..358f0ba 100644 --- a/sound/soc/fsl/mpc8610_hpcd.c +++ b/sound/soc/fsl/mpc8610_hpcd.c @@ -345,8 +345,10 @@ static int mpc8610_hpcd_probe(struct platform_device *pdev) } machine_data = kzalloc(sizeof(struct mpc8610_hpcd_data), GFP_KERNEL); - if (!machine_data) - return -ENOMEM; + if (!machine_data) { + ret = -ENOMEM; + goto error_alloc; + } machine_data->dai[0].cpu_dai_name = dev_name(&ssi_pdev->dev); machine_data->dai[0].ops = &mpc8610_hpcd_ops; @@ -494,7 +496,7 @@ static int mpc8610_hpcd_probe(struct platform_device *pdev) ret = platform_device_add(sound_device); if (ret) { dev_err(&pdev->dev, "platform device add failed\n"); - goto error; + goto error_sound; } dev_set_drvdata(&pdev->dev, sound_device); @@ -502,14 +504,12 @@ static int mpc8610_hpcd_probe(struct platform_device *pdev) return 0; +error_sound: + platform_device_unregister(sound_device); error: - of_node_put(codec_np); - - if (sound_device) - platform_device_unregister(sound_device); - kfree(machine_data); - +error_alloc: + of_node_put(codec_np); return ret; } -- 2.7.4
