[Xen-devel] [PATCH v2 00/12] pci: expand usage of pci_sbdf_t

[Roger Pau Monne <roger.pau@xxxxxxxxxx>]

IMO pci_sbdf_t it's nicer to use than passing around a sbdf in multiple
fields. However it's hard to expand the usage of pci_sbdf_t in the code
base without changing some of the core pci functions and the pci_dev
struct fields, hence this patch set.

Note there's still more low hanging fruit that could benefit from
switching to pci_sbdf_t, this patch series just changes some of the more
core pci functions to use pci_sbdf_t.

This series should not introduce any functional changes.

Roger Pau Monne (12):
  pci: introduce a devfn field to pci_sbdf_t
  pci: introduce a pci_sbdf_t field to pci_dev
  pci: make PCI_SBDF return a pci_sbdf_t
  pci: make PCI_SBDF2 return a pci_sbdf_t
  pci: make PCI_SBDF3 return a pci_sbdf_t
  pci: switch pci_conf_read8 to use pci_sbdf_t
  pci: switch pci_conf_read16 to use pci_sbdf_t
  pci: switch pci_conf_read32 to use pci_sbdf_t
  pci: switch pci_conf_write8 to use pci_sbdf_t
  pci: switch pci_conf_write16 to use pci_sbdf_t
  pci: switch pci_conf_write32 to use pci_sbdf_t
  print: introduce a format specifier for pci_sbdf_t
