From 4596fde5401679f062336c6dbad8d9e4043858c2 Mon Sep 17 00:00:00 2001 From: Hemant Gupta Date: Mon, 16 Apr 2012 14:57:40 +0530 Subject: [PATCH] Bluetooth: mgmt: Fix address type while loading Long Term Key This patch fixes the address type while loading long term keys when BT is switched on. Without this fix pairing is reinitated even though LTK exists for remote device because of mismatch of address type.
