commit 5e316d34b53039346e252d0019e2f4167af2c0ef upstream.
When populating "ranges" property for a PCI bridge or endpoint,
of_pci_prop_ranges() incorrectly uses the CPU address of the resource. In
such PCI nodes, the window should instead be in PCI address space. Call
pci_bus_address() on the resource in order to obtain the PCI bus address.

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.
