Subject: iommu/amd: Fix missing iommu_shutdown initialization in passthrough
mode
From: Shuah Khan <[email protected]>
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.
