Subject: Bluetooth: Access RFCOMM session addresses through L2CAP channel
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=24bc10cad3a76a4fc0f96a7220d4fe02379826d2;p=openwrt%2Fstaging%2Fblogic.git

Bluetooth: Access RFCOMM session addresses through L2CAP channel

The L2CAP socket structure does not contain the address information
anymore. They need to be accessed through the L2CAP channel.
