[PATCH v2] soc: ti: knav_dma: make of_device_ids const.

From: Arvind Yadav
Date: Mon Jun 19 2017 - 01:48:57 EST


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