Alex Deucher d08d692ebb drm/amdgpu: improve error handling in pcie_bw
1. Initialize the counters to 0 in case the callback
   fails to initialize them.
2. The counters don't exist on APUs so return an error
   for them.
3. Return an error if the callback doesn't exist.

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.
