The only iommu function call in this driver is a tegra_dev_iommu_get_stream_id() which does not allocate anything and does not take any reference. More-over, what is freed is "se->dev" which has been devm_kzalloc()'ed in the probe. So there is no point in calling iommu_fwspec_free() in the remove function. Remove this incorrect function call.
