commit84e1b4045dupstream. Aardvark controller has something like config space of a Root Port available at offset 0x0 of internal registers - these registers are used for implementation of the emulated bridge. The default value of Class Code of this bridge corresponds to a RAID Mass storage controller, though. (This is probably intended for when the controller is used as Endpoint.) Change the Class Code to correspond to a PCI Bridge. Add comment explaining this change.

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.
