PCI-2.2 VPD entries have a maximum size of 32k, but might actually
be smaller than that. To figure out the actual size one has to read
the VPD area until the 'end marker' is reached.
Trying to read VPD data beyond that marker results in 'interesting'
effects, from simple read errors to crashing the

Hi Hannes,
[auto build test WARNING on pci/next]
[also build test WARNING on v4.4-rc5 next-20151217]
url:
https://github.com/0day-ci/linux/commits/Hannes-Reinecke/pci-Update-VPD-definitions/20151217-160050
base: https://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci.git next
reproduce:
Tested with a HP AE311-60001 PCIe card. It used to repeat the same VPD every 4k
for 32k now only the 154 bytes are returned and lspci - reports that the
data up
to and including the end and that the check sum is good:

PCI-2.2 VPD entries have a maximum size of 32k, but might actually
be smaller than that. To figure out the actual size one has to read
the VPD area until the 'end marker' is reached.
