From 15c4794fe247d85ce38eb5f5e2a5855d996f56cd Mon Sep 17 00:00:00 2001 From: Anderson Briglia Date: Mon, 21 Feb 2011 15:09:23 -0300 Subject: [PATCH] Bluetooth: Fix LE conn creation This patch prevents a crash when remote host tries to create a LE link which already exists. i.e.: call l2test twice passing the same parameters.
