Subject: [PATCH] virtio: virtio_mmio: make of_device_ids const.
Date: Mon, 19 Jun 2017 11:44:41 +0530 [thread overview]
Message-ID: <f31acbc59cd01a42749c31b6558eefbce508e730.1497852750.git.arvind.yadav.cs@gmail.com> (raw)
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.
