From 1c1697c0cad41fa468e3cb6061ce74debb4f3733 Mon Sep 17 00:00:00 2001 From: Marcel Holtmann Date: Sun, 29 Jun 2014 13:41:51 +0200 Subject: [PATCH] Bluetooth: Update background scanning from hci_conn_params_clear When calling hci_conn_params_clear function, it should update the background scanning properly and not require a separate call to update it. For the case when the function is used during unregister of a controller, an extra safe guard is but in place.
