From: Rikard Falkeborn Date: Sat, 4 Dec 2021 23:33:01 +0100 Subject: iommu/arm-smmu-v3: Constify arm_smmu_mmu_notifier_ops Git-commit: 17d9a4b43b284c333bf2c0c347da28bf22fe7a97 Patch-mainline: v5.17-rc1 References: bsc#1205701 The only usage of arm_smmu_mmu_notifier_ops is to assign its address to the ops field in the mmu_notifier struct, which is a pointer to const struct mmu_notifier_ops. Make it const to allow the compiler to put it in read-only memory.
