From mboxrd@z Thu Jan 1 00:00:00 1970 From: Bhumika Goyal Subject: [PATCH 2/3] drivers: iommu: arm-smmu-v3: constify iommu_gather_ops structures Date: Tue, 25 Oct 2016 23:36:11 +0530 Message-ID: <1477418772-12184-3-git-send-email-bhumirks@gmail.com> References: <1477418772-12184-1-git-send-email-bhumirks@gmail.com> Return-path: In-Reply-To: <1477418772-12184-1-git-send-email-bhumirks@gmail.com> Sender: linux-kernel-owner@vger.kernel.org To: will.deacon@arm.com, robin.murphy@arm.com, joro@8bytes.org, linux-arm-kernel@lists.infradead.org, linux-kernel@vger.kernel.org, iommu@lists.linux-foundation.org, julia.lawall@lip6.fr Cc: Bhumika Goyal List-Id: iommu@lists.linux-foundation.org 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.
