Subject: [PATCH 1/8] ASoC: soc-pcm: check DAI activity under soc_pcm_apply_symmetry()
Date: 05 Mar 2021 09:59:36 +0900 [thread overview]
Message-ID: <87sg5apg93.wl-kuninori.morimoto.gx@renesas.com> (raw)
In-Reply-To: <87tupqpg9x.wl-kuninori.morimoto.gx@renesas.com>
From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>
soc_pcm_apply_symmetry() is used like below in all cases.
if (snd_soc_dai_active(dai)) {
err = soc_pcm_apply_symmetry(fe_substream, dai);
...
}
Because of this style, the code is deep nested.
This patch checks it under soc_pcm_apply_symmetry(), and makes code simple.
static int soc_pcm_apply_symmetry(...)
{
...
=> if (!snd_soc_dai_active(...))
return 0;
...
}
=> ret = soc_pcm_apply_symmetry();
if (ret < 0)
...
