[PATCH v3 0/7] iommu/vt-d: Some cleanups

[Lu Baolu <baolu.lu@linux.intel.com>]

Hi,

This series includes some cleanups in the Intel IOMMU implementation
after the IOMMU core implemented the blocking domain. The cleanup work
is mainly in the attach_dev/device_probe/device_release paths.

Please help to review.

Best regards,
baolu

Change log:
v3:
 - Disable PCI capabilities (PASID/ATS/PRI) when there's no domain
   attached to the device.

v2:
 - https://lore.kernel.org/linux-iommu/20221108073408.1005721-1-baolu.lu@linux.intel.com/
 - Reorder the patches to make the device_block_translation() work with
   the existing path first.
 - Add a new patch to improve iommu_enable_pci_caps().

v1:
 - https://lore.kernel.org/linux-iommu/20221103055329.633052-1-baolu.lu@linux.intel.com/
