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.

Both queued.
Thx.
