[PATCH 2/3] ASoC: soc.h: fixup return timing for snd_soc_fixup_dai_links_platform_name()

[Kuninori Morimoto]

From: Kuninori Morimoto <kuninori.morimoto.gx at renesas.com>

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;
	}
