Subject: staging: make i2c device id constant
X-Git-Url: http://git.mmlx.us/?a=commitdiff_plain;h=b76a32638d9d7d6b421fccce02e667007509bd7b;p=linux-edison.git

staging: make i2c device id constant

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:
