[PATCH 7/14] drivers/media/pci/ngene/ngene-core.c: fix error return code

From: Peter Senna Tschudin
Date: Thu Sep 06 2012 - 11:26:23 EST


From: Peter Senna Tschudin <peter.senna@xxxxxxxxx>

Convert a nonnegative error return code to a negative one, as returned
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>
