Hi Dave,

Just one fixup patch to avoid Exynos DRM driver from being broken with enhancement patch series of IOMMU framework[1]. This patch just makes it reuse default IOMMU domain instead of allocating a fake one.

Ps. We'd like to push this one to help enhancing the IOMMU and DMA-IOMMU frameworks in v4.20

Please kindly let me know if there is any problem.
