| 36 | * For fixed hardware buttons, we fabricate acpi_devices with HID
|
| 37 | * ACPI_BUTTON_HID_POWERF or ACPI_BUTTON_HID_SLEEPF. Fixed hardware
|
| 38 | * signals only an event; it doesn't supply a notification value.
|
| 39 | * To allow drivers to treat notifications from fixed hardware the
|
| 40 | * same as those from real devices, we turn the events into this
|
| 41 | * notification value.
