Subject: [PATCH] afs: delete double assignment
Date: Mon, 28 Jul 2014 20:54:58 +0530	[thread overview]
Message-ID: <20140728152457.GA2901@himangi-Dell> (raw)

A simplified version of Coccinelle semantic match that finds this problem is as
follows:

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

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