Subject: [PATCH 3/14] drivers/media/platform/blackfin/bfin_capture.c: fix error return code
Date: Thu,  6 Sep 2012 17:23:58 +0200	[thread overview]
Message-ID: <1346945041-26676-11-git-send-email-peter.senna@gmail.com> (raw)

From: Peter Senna Tschudin <peter.senna@gmail.com>

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>
