Logan Gunthorpe 33970cf511 PCI: Fix Switchtec DMA aliasing quirk dmesg noise 
[ Upstream commit 742bbe1ee3 ]

Currently the Switchtec quirk runs on all endpoints in the switch,
including all the upstream and downstream ports.  These other functions do
not contain BARs, so the quirk fails when trying to map the BAR and prints
the error "Cannot iomap Switchtec device".  The user will see a few of
these useless and scary errors, one for each port in the switch.

At most, the quirk should only run on either a management endpoint
(PCI_CLASS_MEMORY_OTHER) or an NTB endpoint (PCI_CLASS_BRIDGE_OTHER).
However, the quirk is useless except in NTB applications, so we will
only run it when the class is PCI_CLASS_BRIDGE_OTHER.

Switch to using DECLARE_PCI_FIXUP_CLASS_FINAL and only match
PCI_CLASS_BRIDGE_OTHER.

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.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
