Subject[PATCH 4/9] sound/soc/omap/am3517evm.c: fix error return code
Date
From: Julia Lawall <Julia.Lawall@lip6.fr>

It was forgotten to initialize ret to the result of calling
snd_soc_dai_set_sysclk, unlike at the other calls in the same function.

A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)

// <smpl>
(
if@p1 (\(ret < 0\|ret != 0\))
{ ... return ret; }
|
ret@p1 = 0
)
... when != ret = e1
when != &ret
*if(...)
{
... when != ret = e2
when forall
return ret;
}

// </smpl>

Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr>
