Subject: [PATCH] iommu/arm-smmu-v3-iommufd: Separate vDEVICE allocation list

Stephen Rothwell reports htmldocs warnings when merging iommufd tree:

Documentation/userspace-api/iommufd:335: include/uapi/linux/iommufd.h:456: ERROR: Unexpected indentation. [docutils]
Documentation/userspace-api/iommufd:335: include/uapi/linux/iommufd.h:457: WARNING: Block quote ends without a blank line; unexpected unindent. [docutils]

Fix them by separating vDEVICE allocation list from preceding paragraph.

Fixes: 9f0b286fe40130 ("iommu/arm-smmu-v3-iommufd: Allow attaching nested domain for GBPA cases")

  * It's suggested to allocate a vDEVICE object carrying vSID and then re-attach
  * the nested domain, as soon as the vSID is available in the VMM level:
+ *
  * - when Cfg=translate, a vDEVICE must be allocated prior to attaching to the
  *   allocated nested domain, as CD/ATS invalidations and vevents need a vSID.
  * - when Cfg=bypass/abort, a vDEVICE is not enforced during the nested domain
