Subject: [PATCH] Bluetooth: Return NOTIFY_DONE for hci_suspend_notifier

From: Max Chou <max.chou@...ltek.com>

The original return is NOTIFY_STOP, but notifier_call_chain would stop
the future call for register_pm_notifier even registered on other Kernel
modules with the same priority which value is zero.
