[alsa-devel] [PATCH 1/3] ASoC: soc-core: manage platform name under snd_soc_init_platform()

[Kuninori Morimoto]

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

Now "platform" is controlled by snd_soc_dai_link_component,
thus its "name" can be initialized in snd_soc_init_platform().
This patch do it.
