If anyone has any objections, please let me know. ------------------ From: Shuah Khan commit f2f12b6fc032c7b1419fd6db84e2868b5f05a878 upstream. The iommu_shutdown callback is not initialized when the AMD IOMMU driver runs in passthrough mode. Fix that by moving the callback initialization before the check for passthrough mode.
