Subject: [PATCH] Bluetooth: btusb: BTUSB_WAKEUP_DISABLE prevents wake
Git-commit: 34a68655a1414a34cc950b7fc5478a1b4f0db9b8
Patch-mainline: v5.9-rc1
References: jsc#SLE-13430
When the BTUSB_WAKEUP_DISABLE flag is set, always return true for
prevent wake. This tells the suspend notifier not to prepare the
controller for reconnections during suspend.
