Register iommu_ops at the end of successful probe instead of doing that unconditionally. This makes Exynos IOMMU driver ready for deferred probe caused by not-yet-available clocks. Signed-off-by: Marek Szyprowski <m.szyprowski@samsung.com> --- I'm sorry for the confussing patch number. This patch got lost while rebasing, but it should belong to the "Exynos IOMMU: improve clock management" patchset.
