However, the _FIT is defined to return a data in the format of a series of NFIT type structure entries and as a method, has an acpi_object header rather tahn an acpi_table_header. To address the differences, explicitly save the acpi_table_header from the NFIT, since it is accessible through /sys, and change the nfit pointer in the acpi_desc structure to point to the table entries rather than the headers.
