Merge branches 'acpi-pm', 'acpi-sleep' and 'acpi-button'
* acpi-pm: ACPI / PM: Use ACPI_COMPANION() instead of ACPI_HANDLE() ACPI / PM: Always enable wakeup GPEs when enabling device wakeup ACPI / PM: Revork the handling of ACPI device wakeup notifications PM: Create PM workqueue if runtime PM is not configured too * acpi-sleep: ACPI / sleep: Do not save NVS for new machines to accelerate S3 * acpi-button: ACPI / button: Do not propagate wakeup-from-suspend events
