[PATCH 1/12] arch/arm: Correct size given to memset

[Julia Lawall]

From: Julia Lawall <julia at diku.dk>

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>
