[PATCH v1 1/2] ACPI: SPCR: Prefix error messages with FW_BUG

From: Andy Shevchenko
Date: Wed Mar 22 2023 - 06:26:35 EST


The table values that are not defined in the specification are
considered non-fatal errors in the code. However, they are for
sure the bugs in the firmware. Point this out in the message by
prefixing them with FW_BUG.
