Subject[PATCH 2/3] staging: make USB device id constant
From: Márton Németh <nm127@freemail.hu>

The id_table field of the struct usb_device_id is constant in <linux/usb.h>
so it is worth to make the initialization data also constant.

The semantic match that finds this kind of pattern is as follows:
(http://coccinelle.lip6.fr/)
