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.
