[PATCH 11/25] pcmcia: fix error return code

From: Julia Lawall
Date: Sun Dec 29 2013 - 16:55:22 EST


From: Julia Lawall <Julia.Lawall@xxxxxxx>

Set the return variable to an error code as done elsewhere in the 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>
