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

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

This change includes cleanups and refactoring in the Intel iommu driver
related to the use of the iommu_ops->release_domain.

There are two parts of this topic:
[ ] Introduce release_domain and fix a kernel NULL pointer dereference
issue in the intel iommu driver.
[x] A follow-up series to cleanup intel iommu driver.

Best regards,
baolu
