Ilpo Järvinen b15f45ab65 PCI: Disable non-claimed bridge window
If clipping or claiming the bridge window fails, the bridge window is left
in a state that does not match the kernel's view on what the bridge window
is.

Disable the bridge window by writing the magic disable value into the Base
and Limit Registers if clipping or claiming failed. To detect if claiming
the resource was successful, add res->parent checks into the bridge setup
functions.

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 reStructuredText 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.
