Hi Joerg,

The following fixes have been queued for v7.1-rc. They aim to fix the
following issues.

- Apply an existing quirk for Q35 graphic device.
- Skip dev_pasid teardown for the blocked domain to avoid out-of-bounds
  access.
- Return early if dev_pasid is missing to prevent NULL dereference or
  UAF.

These patches have been reviewed and tested and are ready for merge.
Please consider them for iommu/fix branch.

Best regards,
baolu
