[PATCH 0/3] PCI VPD access fixes

[Hannes Reinecke]

Hi all,

the current PCI VPD page access assumes that the entire possible VPD
data is readable. However, the spec only guarantees a VPD data up to
the 'end' marker, with everything beyond that being undefined.
This causes a system lockup on certain devices.

With this patch we calculate the actual VPD size, or set it to '0'
if no valid VPD data could be read.

Hannes Reinecke (3):
  pci: Update VPD definitions
  pci: Update VPD size with correct length
  pci: set VPD size to '0' if PCI_VPD_FLAGS_VPD_REF_F0 is set
