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.

Inki Dae
