> Subject: [PATCH 2/2] EDAC/igen6: Convert PCIBIOS_* return codes to errnos
>
> errcmd_enable_error_reporting() uses pci_{read,write}_config_word() that
> return PCIBIOS_* codes. The return code is then returned all the way into the
> probe function igen6_probe() that returns it as is. The probe functions,
> however, should return normal errnos.
>
> Convert PCIBIOS_* returns code using pcibios_err_to_errno() into normal
> errno before returning it from errcmd_enable_error_reporting().

> IBECC")
