From 35364c99d20edc7329843e2a6dad6851d77eafd7 Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Tue, 28 Jan 2014 15:16:50 -0800 Subject: Bluetooth: Refuse peer RFCOMM address reading when not connected When we're not connected the peer address information is undefined. This patch fixes the remote address getting to return a proper error in case the sate is anything else than BT_CONNECTED.
