From 98e0f7ea4a5b4774805c62be104f19abba6187ac Mon Sep 17 00:00:00 2001 From: Marcel Holtmann Date: Sun, 13 Oct 2013 02:23:40 -0700 Subject: Bluetooth: Remove l2cap_conn->src and l2cap_conn->dst usage from L2CAP The l2cap_conn->src and l2cap_conn->dst addresses are just a pointers to hci_conn structure. Use hci_conn->hdev->bdaddr and hci_conn->dst directly instead.
