From b1078ad0be344e7bec6e7991f33df17565d24e08 Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Thu, 9 Feb 2012 17:21:16 +0200 Subject: Bluetooth: Add Device Unpaired mgmt event This patch add a new Device Unpaired mgmt event. This will be sent to all mgmt sockets except the one that requested unpairing (that socket will get a command complete instead). The event is also reserved for future SMP updates where a remote device will be able to request pairing revocation from us.
