Subject: [alsa-devel] [PATCH v2 08/14] ASoC: soc-core: remove snd_soc_rtdcom_del_all()
Date: 12 Sep 2019 13:42:44 +0900
Message-ID: <875zlyf7ln.wl-kuninori.morimoto.gx@renesas.com> (raw)
In-Reply-To: <87h85if7u8.wl-kuninori.morimoto.gx@renesas.com>


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

If we can use devm_kzalloc(rtd->dev, xxx) for rtdcom,
we don't need to call snd_soc_rtdcom_del_all() for kfree().
This patch uses devm_kzalloc(rtd->dev, xxx) for rtdcom,
and remove snd_soc_rtdcom_del_all().
