From 31919140ff8c88c236f697baa28a6305df45e4ea Mon Sep 17 00:00:00 2001 From: Arvind Yadav Date: Mon, 19 Jun 2017 11:44:41 +0530 Subject: [PATCH] virtio: virtio_mmio: make of_device_ids const. of_device_ids are not supposed to change at runtime. All functions working with of_device_ids provided by work with const of_device_ids. So mark the non-const structs as const.
