If anyone has any objections, please let me know. ------------------ From: Luiz Augusto von Dentz [ Upstream commit 79e562a52adea4afa0601a15964498fae66c823c ] The debug UUID was only getting set if MGMT_OP_READ_EXP_FEATURES_INFO was not called with a specific index which breaks the likes of bluetoothd since it only invokes MGMT_OP_READ_EXP_FEATURES_INFO when an adapter is plugged, so instead of depending hdev not to be set just enable the UUID on any index like it was done with iso_sock_uuid.
