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> Signed-off-by: Julia Lawall <Julia.Lawall@inria.fr> --- sound/soc/pxa/mmp-sspa.c | 1 - 1 file changed, 1 deletion(-)
