mainlining shenanigans
dc98b8480d
Removing the early device registration hook overlooked the fact that it only ran conditionally on a compatible device being present in the DT. With exynos_iommu_init() now running as an unconditional initcall, problems arise on non-Exynos systems when other IOMMU drivers find themselves unable to install their ops on the platform bus, or at worst the Exynos ops get called with someone else's domain and all hell breaks loose. The global ops/cache setup could probably all now be triggered from the first IOMMU probe, as with dma_dev assigment, but for the time being the simplest fix is to resurrect the logic from commit |

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
