Subject: [PATCH 2/6] drivers/media/platform/mx2_emmaprp.c: adjust inconsistent IS_ERR and PTR_ERR
Date: Sat, 25 Aug 2012 21:57:05 +0200	[thread overview]
Message-ID: <1345924629-16584-3-git-send-email-Julia.Lawall@lip6.fr> (raw)
In-Reply-To: <1345924629-16584-1-git-send-email-Julia.Lawall@lip6.fr>

From: Julia Lawall <Julia.Lawall@lip6.fr>

Change the call to IS_ERR to test the value that was just initialized and
is returned using PTR_ERR.

The semantic match that finds this problem is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>

expression e,e1;
@@

(
if (IS_ERR(e)) { ... PTR_ERR(e) ... }
|
if (IS_ERR(e=e1)) { ... PTR_ERR(e) ... }
|
*if (IS_ERR(e))
 { ...
*  PTR_ERR(e1)
   ... }
)
// </smpl>
