From f706adfeade767d2194c9f39c0f75e944b0bdd23 Mon Sep 17 00:00:00 2001 From: Andrei Emeltchenko Date: Thu, 18 Oct 2012 13:16:19 +0300 Subject: [PATCH] Bluetooth: AMP: Get amp_mgr reference in HS hci_conn When assigning amp_mgr in hci_conn (type AMP_LINK) get also reference. In hci_conn_del those references would be put for both conn types AMP_LINK and ACL_LINK associated with amp_mgr.
