Bug description:
[Impact]
The new feature added by below commit let BT device to wake up the system
from S3 or s2idle.
a0085f2510e8 ("Bluetooth: btusb: driver to enable the usb-wakeup feature")
But this feature also wakes up the system randomly from an unpaired BLE
device by its advertising packets.
[Fix]
There is no easy way to fix this and requires firmware update, so current
solution for this is to revert it.
1ffdb51f28e8 ("Revert "Bluetooth: btusb: driver to enable the usb-wakeup
feature"")
[Test]
Verified on machines which has paired BLE devices, and can't be waken up by
BT devices after entered suspended.
[Regression]
Yes, it reverts the feature by waking up system from s2idle by paired BT
devices, but this feature introduces regression, so I'd suggest to revert it.
