Subject: [PATCH 0/2] iommu: Fix domain check on device release

This is a follow-up to the discussion thread here:

https://lore.kernel.org/linux-iommu/20240221154012.GC13491@ziepe.ca/

It fixes a NULL pointer reference in the Intel iommu driver and
strengthens the iommu core to possibly prevent similar failures in other
iommu drivers.

Best regards,
baolu
