Simplify the interface so the caller need only supply "device". This makes it obvious that "wakeup", i.e., &device->wakeup, can never be NULL, so remove the unnecessary check for that.

Add comments to identify the power button, lid, and sleep button devices. The "PNP" prefix is owned by Microsoft, so they distribute the canonical list of "PNP" IDs.

There is no standard ACPI header, though, so less common layouts with different field sizes required custom parsers to go through their subtable entry list. Create the infrastructure for adding different table types so parsing the entries array may be more reused for all ACPI system tables and the common code doesn't need to be duplicated.
