Subject[PATCH 4.14 54/74] Bluetooth: Fix memory leak in hci_connect_le_scan
Date
From: Navid Emamdoost <navid.emamdoost@gmail.com>

commit d088337c38a5cd8f0230fbf2d514ff7672f9d0d3 upstream.

In the implementation of hci_connect_le_scan() when conn is added via
hci_conn_add(), if hci_explicit_conn_params_set() fails the allocated
memory for conn is leaked. Use hci_conn_del() to release it.

Fixes: f75113a26008 ("Bluetooth: add hci_connect_le_scan")
