    Subject[PATCH 2/2] iommu/arm-smmu: Propagate errors from platform_get_irq()
    Date
    The driver overrides the error code returned by platform_get_irq() to
    -ENODEV. Switch to propagating the error code upstream so that errors
    such as -EPROBE_DEFER are handled.

    Fixes: 9ec36cafe43b ("of/irq: do irq resolution in platform_get_irq")
