[PATCH] ACPI: NFIT: Fix support for variable 'SPA' structure size

2021-05-07 Thread Dan Williams
ACPI 6.4 introduced the "SpaLocationCookie" to the NFIT "System Physical Address (SPA) Range Structure". The presence of that new field is indicated by the ACPI_NFIT_LOCATION_COOKIE_VALID flag. Pre-ACPI-6.4 firmware implementations omit the flag and maintain the original size of the structure.
