3.2-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ulisses Furquim <ulis...@profusion.mobi>
commit f1e91e1640d808d332498a6b09b2bcd01462eff9 upstream.
The handling of SCO audio links and the L2CAP protocol are essential to
any system with Bluetooth thus are always compiled in from now on.
