From 8bfebd2651ccc99bc7db7a01bcea3371e1b36076 Mon Sep 17 00:00:00 2001
From: Robin Murphy <robin.murphy@arm.com>
Date: Tue, 9 Jan 2018 16:17:26 +0000
Subject: [PATCH 0429/1795] iommu/ipmmu-vmsa: Remove redundant of_iommu_init_fn
hook
Having of_iommu_init() call ipmmu_init() via ipmmu_vmsa_iommu_of_setup()
does nothing that the subsys_initcall wouldn't do slightly later anyway,
since probe-deferral of masters means it is no longer critical to
register the driver super-early. Clean it up.
