From be9d122730c878baafe11e70d1436faac229f2fc Mon Sep 17 00:00:00 2001 From: Marcel Holtmann Date: Tue, 8 Nov 2005 09:57:38 -0800 Subject: [Bluetooth]: Remove the usage of /proc completely This patch removes all relics of the /proc usage from the Bluetooth subsystem core and its upper layers. All the previous information are now available via /sys/class/bluetooth through appropriate functions. Signed-off-by: Marcel Holtmann Signed-off-by: David S.
