Subject: [alsa-devel] [PATCH v2 09/14] ASoC: soc-core: use devm_kzalloc() for rtd
Date: 12 Sep 2019 13:43:17 +0900 [thread overview]
Message-ID: <874l1if7kq.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>
Current rtd, rtd->dev, rtd->codec_dais are created by normal kzalloc(),
but we want to use devm_kzalloc() as much as possible.
Created rtd->dev is registered by device_register() at
soc_new_pcm_runtime(), and it will be freed at
soc_free_pcm_runtime() by device_unregister().
This means, if we can use devm_kzalloc(rtd->dev, xxx) for
rtd / rtd->codec_dais, all these are automatically freed
via soc_free_pcm_runtime().
This patch uses devm_kzalloc(rtd->dev, xxx) for rtd / rtd->codec_dais.
