From 53c92d793395fdab9edbd2f79b084bb6b2e6ae79 Mon Sep 17 00:00:00 2001 From: Robin Murphy <Robin.Murphy@arm.com> Date: Thu, 7 Apr 2016 18:42:05 +0100 Subject: iommu: of: enforce const-ness of struct iommu_ops As a set of driver-provided callbacks and static data, there is no compelling reason for struct iommu_ops to be mutable in core code, so enforce const-ness throughout.
