This is a follow-up to the conversation here:
https://lore.kernel.org/r/1cdda5f1-e1ea-af9f-cfbe-952b7d37e246@gmail.com
about how and whether we should validate the contents of VPD.

My proposal is to basically do minimal validation since the kernel really
doesn't care about the actual *contents* of VPD and mainly provides an
access mechanism (although there a few drivers that get part numbers and
maybe even clocking information from VPD).

I welcome any feedback!

Bjorn Helgaas (5):
  PCI/VPD: Correct diagnostic for VPD read failure
  PCI/VPD: Check Resource tags against those valid for type
  PCI/VPD: Consolidate missing EEPROM checks
  PCI/VPD: Don't check Large Resource types for validity
  PCI/VPD: Allow access to valid parts of VPD if some is invalid
