    Subject[patch V2 11/17] iommu/of: Adjust system_state check
    To enable smp_processor_id() and might_sleep() debug checks earlier, it's
    required to add system states between SYSTEM_BOOTING and SYSTEM_RUNNING.

    Adjust the system_state check in of_iommu_driver_present() to handle the
    extra states.
