[PATCH 11/12] net/mac80211: Correct size given to memset
From: Julia Lawall
Date: Wed Dec 09 2009 - 14:26:13 EST
From: Julia Lawall <julia@xxxxxxx>
Memset should be given the size of the structure, not the size of the pointer.
The semantic patch that makes this change is as follows:
(http://coccinelle.lip6.fr/)
// <smpl>
@@
type T;
T *x;
expression E;
@@
memset(x, E, sizeof(
+ *
x))
// </smpl>
