Subject: [PATCH] arch/arm/mach-s3c24xx/mach-h1940.c: delete double assignment
Date: Wed, 12 Sep 2012 21:28:55 +0200	[thread overview]
Message-ID: <1347478135-744-1-git-send-email-Julia.Lawall@lip6.fr> (raw)

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

Delete successive assignments to the same location.

A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)

// <smpl>
@@
expression i;
@@

*i = ...;
 i = ...;
// </smpl>

Not compiled, and this may change the behavior of the code.  Without this
change, check_gpio2 could possibly be used uninitialized later.
