Subject: [PATCH 2/3] drivers: iommu: arm-smmu-v3: constify iommu_gather_ops structures
Date: Tue, 25 Oct 2016 23:36:11 +0530	[thread overview]
Message-ID: <1477418772-12184-3-git-send-email-bhumirks@gmail.com> (raw)
In-Reply-To: <1477418772-12184-1-git-send-email-bhumirks@gmail.com>

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.
