From 60f2a3ed7beb2e9b8f2c63de0895f587e0c1ca76 Mon Sep 17 00:00:00 2001 From: Marcel Holtmann Date: Tue, 1 Oct 2013 22:59:20 -0700 Subject: [PATCH] Bluetooth: Use only 2 bits for controller type information The controller type is limited to BR/EDR/LE and AMP controllers. This can be easily encoded with just 2 bits and still leave enough room for future controller types.
