From: Bhumika Goyal Date: Tue, 25 Oct 2016 18:06:11 +0000 (+0530) Subject: iommu/arm-smmu: Constify iommu_gather_ops structures X-Git-Tag: v5.15~12252^2^3~1^2~18 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=ca297aad17e1dfbce1d7e9e162fcaf74f7c87eb5;p=platform%2Fkernel%2Flinux-starfive.git iommu/arm-smmu: Constify iommu_gather_ops structures Check for iommu_gather_ops structures that are only stored in the tlb field of an io_pgtable_cfg structure. The tlb field is of type const struct iommu_gather_ops *, so iommu_gather_ops structures having this property can be declared as const.
