[Patch V2 0/4] Code refine for Intel IOMMU

[Wei Yang]

These four patches try to refine the Intel IOMMU.

Patch 1/2 tries to make it more user friendly by add a zero-sized array in
some dmar data structure.
Patch 3 move the ckeck of Register Base Address ahead to avoid cleanup when it
is NULL.
Patch 4 re-use dmar_walk_dmar_table() to make the code easy to understand.

V2:
  * add patch 3 and 4

Wei Yang (4):
  iommu/vt-d: replace *hdr with hdr[0] in struct dmar_drhd_unit
  iommu/vt-d: use zero-sized array in DMAR related ACPI structures
  iommu/vt-d: check Register Base Address at the beginning of
    dmar_parse_one_drhd()
  iommu/vt-d: refine dmar_acpi_dev_scope_init() with
    dmar_walk_dmar_table()
