From 0684e5f9fb9e3f7e168ab831dfca693bcb44805b Mon Sep 17 00:00:00 2001 From: Marcel Holtmann Date: Mon, 9 Feb 2009 02:48:38 +0100 Subject: Bluetooth: Use general bonding whenever possible When receiving incoming connection to specific services, always use general bonding. This ensures that the link key gets stored and can be used for further authentications.
