[PATCH 0/3] constify iio i2c_device_id

[Arvind Yadav]

i2c_device_id are not supposed to change at runtime. All functions
working with i2c_device_id provided by <linux/i2c.h> work with
const i2c_device_id. So mark the non-const structs as const.

Applied to the togreg branch of iio.git and pushed out as testing
for the autobuilders to play with it.
