Subject: [PATCH 1/2] iommu/arm-smmu-qcom: Fix missing adreno_smmu's
Date: Tue,  2 May 2023 09:09:47 -0700	[thread overview]
Message-ID: <20230502160950.1758826-1-robdclark@gmail.com> (raw)

From: Rob Clark <robdclark@chromium.org>

When the special handling of qcom,adreno-smmu was moved into
qcom_smmu_create(), it was overlooked that we didn't have all the
required entries in qcom_smmu_impl_of_match.  So we stopped getting
adreno_smmu_priv on sc7180, breaking per-process pgtables.

Fixes: 30b912a03d91 ("iommu/arm-smmu-qcom: Move the qcom,adreno-smmu check into qcom_smmu_create")
