From: Archie Pusaka <apusaka@chromium.org>
[ Upstream commit f48735a9aaf8258f39918e13adf464ccd7dce33b ]
To prevent multiple conn complete events, we shouldn't look up the conn with hci_lookup_le_connect, since it requires the state to be BT_CONNECT. By the time the duplicate event is processed, the state might have changed, so we end up processing the new event anyway.
Change the lookup function to hci_conn_hash_lookup_ba.
