0d5370d1d8("PCI: Prevent VPD access for QLogic ISP2722") disabled access to VPD of the ISP2722-based 16/32Gb Fibre Channel to PCIe Adapter because reading past the end of the VPD caused NMIs.104daa71b3("PCI: Determine actual VPD size on first access") limits reads to the actual size of VPD, which should prevent these NMIs.104daa71b3was merged *before*0d5370d1d8, but we think the testing that prompted0d5370d1d8("PCI: Prevent VPD access for QLogic ISP2722") was done with a kernel that lacked104daa71b3. See [1, 2]. Remove the quirk added by0d5370d1d8("PCI: Prevent VPD access for QLogic ISP2722") so customers can read the HBA VPD.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
