4Subject: [PATCH 1/3] ACPI: improve the return values and the log info in the
5 fwts_acpi_handle_fadt_tables function.
6
7If the 32-bit or/and 64-bit point is/are null, reture FWTS_NULL_POINTER instead of FWTS_ERROR.
8Add the error log message for loading FACS/DSDT fail.
9
10It is a prerequisite for ignoring a missing FACS table in hardware-reduced mode.

4Subject: [PATCH 3/3] ACPI: a missing FACS table can be ignored under some
5 circumstances
6
7Both of the FADT fields FIRMWARE_CTRL and X_FIRMWARE_CTRL are
8allowed to be null, if and only if ACPI is operating in hardware-
9reduced mode. If the ACPI tables are from before ACPI 5.0, or if
10ACPI is not operating in hardware-reduced mode, at least one of the
11FIRMWARE_CTRL or X_FIRMWARE_CTRL fields _must_ be non-null.
12
13This patch corrects the logic to ensure that a missing FACS is only
14allowed under the proper circumstances.
