[PATCH 4/4] rtc: rv3029c2: constify i2c_device_id

From: Arvind Yadav
Date: Sat Aug 19 2017 - 15:08:30 EST


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.
