Subject: [PATCH 1/3] iommu: exynos: constify iommu_ops
Date: Mon, 28 Aug 2017 17:42:05 +0530	[thread overview]
Message-ID: <1503922325-25905-1-git-send-email-arvind.yadav.cs@gmail.com> (raw)

iommu_ops are not supposed to change at runtime.
Functions 'iommu_device_set_ops' and 'bus_set_iommu' working with
const iommu_ops provided by <linux/iommu.h>. So mark the non-const
structs as const.
