From b219e3ac66183fc9771b94af931fb5fd41d586ec Mon Sep 17 00:00:00 2001 From: Marcel Holtmann Date: Thu, 6 Jul 2006 12:38:46 +0200 Subject: [Bluetooth] Integrate low-level connections into the driver model This patch integrates the low-level connections (ACL and SCO) into the driver model. Every connection is presented as device with the parent set to its host controller device.
