[PATCH 1/4] ASoC: mmp-sspa: drop unneeded snd_soc_dai_set_drvdata

[Julia Lawall]

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>
