Subject: [PATCH 2/4] ASoC: mxs-saif: drop unneeded snd_soc_dai_set_drvdata
Date: Sat, 13 Feb 2021 11:19:05 +0100 [thread overview]
Message-ID: <20210213101907.1318496-3-Julia.Lawall@inria.fr> (raw)
In-Reply-To: <20210213101907.1318496-1-Julia.Lawall@inria.fr>
snd_soc_dai_set_drvdata is not needed when the set data comes from
snd_soc_dai_get_drvdata or dev_get_drvdata. The problem was fixed
usingthe following semantic patch: (http://coccinelle.lip6.fr/)
// <smpl>
@@
expression x,y,e;
@@
x = dev_get_drvdata(y->dev)
... when != x = e
- snd_soc_dai_set_drvdata(y,x);
@@
expression x,y,e;
@@
x = snd_soc_dai_get_drvdata(y)
... when != x = e
- snd_soc_dai_set_drvdata(y,x);
// </smpl>
In this case, the whole probe function then does nothing, so drop it.
