In the Linux kernel, the following vulnerability has been resolved:iommu/arm-smmu-qcom: Add SM6115 MDSS compatibleAdd the SM6115 MDSS compatible to clients compatible list, as it also
needs that workaround.
Without this workaround, for example, QRB4210 RB2 which is based on
SM4250/SM6115 generates a lot of smmu unhandled context faults during
boot:arm_smmu_context_fault: 116854 callbacks suppressed
