From 6ec5bcadc21e13ceba8c144e4731eccac01d04f7 Mon Sep 17 00:00:00 2001 From: Vishal Agarwal Date: Mon, 16 Apr 2012 14:44:44 +0530 Subject: Bluetooth: Temporary keys should be retained during connection If a key is non persistent then it should not be used in future connections but it should be kept for current connection. And it should be removed when connecion is removed.
