From 4a50724eb0ba96b849f4a0c8da28b2b796859f9e Mon Sep 17 00:00:00 2001 From: Kuninori Morimoto Date: Mon, 22 Mar 2021 11:48:40 +0900 Subject: [PATCH] ASoC: soc.h: fixup return timing for snd_soc_fixup_dai_links_platform_name() Current snd_soc_fixup_dai_links_platform_name() creates name first (A), and checks setup target pointer (B), and set it (C). We should check target pointer first IMO. This patch exchange the order to (B) -> (A) -> (C). int snd_soc_fixup_dai_links_platform_name(...) { ... /* set platform name for each dailink */ for_each_card_prelinks(card, i, dai_link) { (A) name = devm_kstrdup(...); if (!name) return -ENOMEM; (B) if (!dai_link->platforms) return -EINVAL; /* only single platform is supported for now */ (C) dai_link->platforms->name = name; } return 0; } Signed-off-by: Kuninori Morimoto Link: https://lore.kernel.org/r/8735wnaoon.wl-kuninori.morimoto.gx@renesas.com Signed-off-by: Mark Brown --- include/sound/soc.h | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) diff --git a/include/sound/soc.h b/include/sound/soc.h index e4161071f300..200815ca4112 100644 --- a/include/sound/soc.h +++ b/include/sound/soc.h @@ -1280,13 +1280,13 @@ int snd_soc_fixup_dai_links_platform_name(struct snd_soc_card *card, /* set platform name for each dailink */ for_each_card_prelinks(card, i, dai_link) { + if (!dai_link->platforms) + return -EINVAL; + name = devm_kstrdup(card->dev, platform_name, GFP_KERNEL); if (!name) return -ENOMEM; - if (!dai_link->platforms) - return -EINVAL; - /* only single platform is supported for now */ dai_link->platforms->name = name; }
