[PATCH 2/2] iommu/arm-smmu: Propagate errors from platform_get_irq()

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") Signed-off-by: Lad Prabhakar --- drivers
