Commit 69d9b312f38a ("iommu/arm-smmu-v3: Support IOMMU_VIOMMU_ALLOC")
started using _iommufd_object_alloc() without importing the IOMMUFD
module namespace, resulting in a modpost warning:
WARNING: modpost: module arm_smmu_v3 uses symbol _iommufd_object_alloc from namespace IOMMUFD, but does not import it.
Commit d68beb276ba2 ("iommu/arm-smmu-v3: Support IOMMU_HWPT_INVALIDATE
using a VIOMMU object") added another warning by using
iommufd_viommu_find_dev():
WARNING: modpost: module arm_smmu_v3 uses symbol iommufd_viommu_find_dev from namespace IOMMUFD, but does not import it.
Import the IOMMUFD module namespace to resolve the warnings.
