From mboxrd@z Thu Jan 1 00:00:00 1970 From: bhumirks@gmail.com (Bhumika Goyal) Date: Tue, 25 Oct 2016 23:36:12 +0530 Subject: [PATCH 3/3] drivers: iommu: io-pgtable-arm: use const and __initconst for iommu_gather_ops structures In-Reply-To: <1477418772-12184-1-git-send-email-bhumirks@gmail.com> References: <1477418772-12184-1-git-send-email-bhumirks@gmail.com> Message-ID: <1477418772-12184-4-git-send-email-bhumirks@gmail.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.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. Also, replace __initdata with __initconst.
