Subject: [PATCH 4/4] drivers/crypto/tegra-aes.c: fix error return code
Date: Mon, 17 Sep 2012 19:28:28 +0200 [thread overview]
Message-ID: <1347902908-19006-4-git-send-email-peter.senna@gmail.com> (raw)
In-Reply-To: <1347902908-19006-1-git-send-email-peter.senna@gmail.com>
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>
