Subject: [PATCH 3/3] staging: make i2c device id constant
From: Márton Németh <nm127@...email.hu>
The id_table field of the struct i2c_driver is constant in <linux/i2c.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/)
// <smpl>
