Bug description:
[Impact]
Commit e42aa2100e022 ("ACPI: button: Install notifier for system
events as well") in OEM-6.11 modified the ACPI button behavior to
send `ACPI_BUTTON_NOTIFY_WAKE` events.
This caused a regression on Dell Optiplex 3040 sending `KEY_POWER`
randomly at runtime.
[Fix]
The commit in the linux-next(6.15-rc) fix the issue
a8605b0ed187 ACPI: button: Only send `KEY_POWER` for
`ACPI_BUTTON_NOTIFY_STATUS`
[Test]
Verify on Dell Optiplex 3040 to see if encounter power button event randomly.
[Where problems could occur]
It ignores the acpi keyevent if the event is ACPI_BUTTON_NOTIFY_WAKE.
It's reasonable to skip this event, or it triggers the KEY_POWER.
