From d215874460e7657b8e104de024140e0932690450 Mon Sep 17 00:00:00 2001 From: Marcel Holtmann Date: Wed, 9 May 2007 09:15:35 +0200 Subject: [PATCH] [Bluetooth] Add HCIUARTGETDEVICE support for HCI line discipline Adding HCIUARTGETDEVICE makes it possible to get the HCI device number that is attached to a given serial device. This is required during the initialization process of some Bluetooth chips.
