From 6898325923f9571fbede3372dc490faa43b3258a Mon Sep 17 00:00:00 2001 From: "Gustavo F. Padovan" Date: Fri, 4 Feb 2011 03:02:31 -0200 Subject: [PATCH] Bluetooth: move l2cap_sock_recvmsg() to l2cap_sock.c It causes the move of the declaration of 3 functions to l2cap.h: l2cap_get_ident(), l2cap_send_cmd(), l2cap_build_conf_req() Signed-off-by: Gustavo F.
