[PATCH] acpi/fadt: check no-zero failures for X_PM* for 6.1 and before

Thu Oct 31 20:50:58 UTC 2019


Starting from ACPI 6.2, X_PM* fields update the descriptions as below

"If this field contains a nonzero value which can be used by the
OSPM, then the PM* field must be ignored by the OSPM."

As a result, skip failures for ACPI 6.2 and later.
