Subject: [PATCH 0/8] PCI/VPD: Extend PCI VPD API

This series adds three functions to the PCI VPD API that help to
simplify driver code. First users are sfc and tg3 drivers because
I have test hw. The other users of the VPD API will benefit from a
migration as well.
I'd propose to apply this series via the PCI tree.

Added API calls:

pci_vpd_alloc()
Dynamically allocates a properly sized buffer and reads the VPD into it.

pci_vpd_find_ro_info_keyword()
Locates an info field keyword in the VPD RO section.
pci_vpd_find_info_keyword() can be removed once all
users have been migrated.

pci_vpd_check_csum()
Check VPD checksum based on algorithm defined in the PCI specification.

Tested on a SFN6122F and a BCM95719 card.

Heiner Kallweit (8):
  PCI/VPD: Add pci_vpd_alloc
  PCI/VPD: Add pci_vpd_find_ro_info_keyword and pci_vpd_check_csum
  PCI/VPD: Add missing VPD RO field keywords
  sfc: Use new function pci_vpd_alloc
  sfc: Use new VPD API function pci_vpd_find_ro_info_keyword
  tg3: Use new function pci_vpd_alloc
  tg3: Use new function pci_vpd_check_csum
  tg3: Use new function pci_vpd_find_ro_info_keyword
