commit 3ec8ebd8a5b782d56347ae884de880af26f93996 upstream.
gpu_get_node_map() uses pci_read_config_dword() that returns PCIBIOS_*
codes. The return code is then returned all the way into the module
init function amd64_edac_init() that returns it as is. The module init
functions, however, should return normal errnos.
Convert PCIBIOS_* returns code using pcibios_err_to_errno() into normal
errno before returning it from gpu_get_node_map().
For consistency, convert also the other similar cases which return
PCIBIOS_* codes even if they do not have any bugs at the moment.

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.
