Commit cf04eee8bf0e ("iommu/vt-d: Include ACPI devices in iommu=pt") added for_each_active_iommu() in iommu_prepare_static_identity_mapping() but never used the each element, i.e, "drhd->iommu". drivers/iommu/intel-iommu.c: In function 'iommu_prepare_static_identity_mapping': drivers/iommu/intel-iommu.c:3037:22: warning: variable 'iommu' set but not used [-Wunused-but-set-variable] struct intel_iommu *iommu; Fixed the warning by appending a compiler attribute __maybe_unused for it.
