...test it and report back? Even better if you can fix up any breakage it might cause :) >From 60a288509baa34df6a0bf437c977925a0a617c72 Mon Sep 17 00:00:00 2001 From: Joerg Roedel <jroedel at suse.de> Date: Thu, 9 Apr 2020 13:38:18 +0200 Subject: [PATCH] iommu/exynos: Get rid of 'struct exynos_iommu_owner' Remove 'struct exynos_iommu_owner' and replace it with a single-linked list of 'struct sysmmu_drvdata'. The first item in the list acts as a replacement for the previous exynos_iommu_owner structure. The iommu_device member of the first list item is reported to the IOMMU cor...

It doesn't handle EPROBE_DEFER too. I don't quite understand why probe_device() is called too early, as it is called at the same
