From d088337c38a5cd8f0230fbf2d514ff7672f9d0d3 Mon Sep 17 00:00:00 2001 From: Navid Emamdoost Date: Thu, 21 Nov 2019 14:20:36 -0600 Subject: Bluetooth: Fix memory leak in hci_connect_le_scan 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.
