From: Johan Hedberg Date: Tue, 28 Jan 2014 23:16:50 +0000 (-0800) Subject: Bluetooth: Refuse peer RFCOMM address reading when not connected X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=35364c99d20edc7329843e2a6dad6851d77eafd7;p=linux-beck.git 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.
