Subject[PATCH v5 2/5] iommu/arm-smmu: refactor qcom_smmu structure to include single pointer
Date
qcom_smmu_match_data is static and constant so refactor qcom_smmu
to store single pointer to qcom_smmu_match_data instead of
replicating multiple child members of the same and handle the further
dereferences in the places that want them.
