From dee58c1ed5e29eb57fa9358a8ff27848b72f3b7d Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Wed, 9 Jul 2014 12:59:16 +0300 Subject: [PATCH] Bluetooth: Fix incorrectly setting HCI_CONNECTABLE Since page scan might be enabled by Add Device we should not implicitly set connectable whenever something else than Set Connectable changes it. This patch makes sure that we don't set HCI_CONNECTABLE for these cases if there are any entries in the white list.
