[alsa-devel] [PATCH 4/5] ASoC: soc-core: add snd_soc_add_component()

[Kuninori Morimoto]

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

ALSA SoC platform/codec will be replaced to component soon.
But, some function exist in "platform" doesn't exist in "component".
Current soc-core has snd_soc_register_component(), but
doesn't have snd_soc_add_component() like snd_soc_add_platform().
This patch adds it.

This removes error message when kzalloc() failed, because current
checkpatch.pl requests it (commit ebfdc40969f2 ("checkpatch: attempt
to find unnecessary 'out of memory' messages"))
