From dc25306b033cc27ca2a45b4bb307a437092408d1 Mon Sep 17 00:00:00 2001 From: Gustavo Padovan Date: Tue, 15 Oct 2013 19:24:49 -0300 Subject: Bluetooth: Move l2cap_wait_ack() to l2cap_sock.c The wait_ack code has a heavy dependency on the socket data structures and, as of now, it won't be worthless change it to use non-socket structures as the only user of such feature is a socket.
