Arun Easi 7cb1f30423 PCI: Allow VPD access for QLogic ISP2722
commit e00dc69b5f17c444a38cd9745a0f76bc989b3af4 upstream.

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.

104daa71b3 was merged *before* 0d5370d1d8, but we think the testing
that prompted 0d5370d1d8 ("PCI: Prevent VPD access for QLogic ISP2722")
was done with a kernel that lacked 104daa71b3.  See [1, 2].

Remove the quirk added by 0d5370d1d8 ("PCI: Prevent VPD access for QLogic
ISP2722") so customers can read the HBA VPD.

README

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.
