[ Upstream commit 6dfccd13db2ff2b709ef60a50163925d477549aa ]
AMP_MGR is getting derefernced in hci_phy_link_complete_evt(), when called
from hci_event_packet() and there is a possibility, that hcon->amp_mgr may
not be found when accessing after initialization of hcon.
- net/bluetooth/hci_event.c:4945
The bug seems to get triggered in this line:
bredr_hcon = hcon->amp_mgr->l2cap_conn->hcon;
Fix it by adding a NULL check for the hcon->amp_mgr before checking the ev-status.
Fixes:
