Actually, this fixes the issue that block users from seeing VPD data in
"lspci -vvv" listing. My bad in not stating that well in the commit log.
In retrospect, this was mentioned only in a prior e-mail (link[2] above --
sorry about our exchange servers mangling the URL and redirecting it via
proofpoint).
I can re-send the patch to correctly reflect it as a fix. Something like:
Subject: "PCI/VPD: Fix blocking of VPD data in lspci for QLogic 1077:2261"
What do you think?
