Subject: drivers/usb: correct code taking the size of a pointer
From: Julia Lawall <julia@xxxxxxx>
sizeof(chid) is just the size of the pointer. Change it to the size of the
referenced structure.
A simplified version of the semantic patch that finds this problem is as
follows: (http://coccinelle.lip6.fr/)
// <smpl>
@@
expression *x;
expression f;
type T;
@@
*f(...,(T)x,...)
// </smpl>
