From b7d839bfff78a01705f3d7b0acd5257dc7b067c9 Mon Sep 17 00:00:00 2001 From: Vinicius Costa Gomes Date: Fri, 27 Jul 2012 19:32:58 -0300 Subject: [PATCH] Bluetooth: Refactor SCO connection into its own function We can do the same that we did for the other link types, for SCO connections. The only thing that's worth noting is that as SCO links need an ACL link, this functions uses the function that adds an ACL link.
