From 4364f2e91f0d44fa0e233d2a55e3ec35053d9bd9 Mon Sep 17 00:00:00 2001 From: Alain Michaud Date: Thu, 23 Apr 2020 14:43:29 +0000 Subject: Bluetooth: allow scatternet connections if supported. This change allows scatternet connections to be created if the controller reports support and the HCI_QUIRK_VALID_LE_STATES indicates that the reported LE states can be trusted.
