From 5ea234d3e5ff9b6e5c82bde5979307213dde249d Mon Sep 17 00:00:00 2001 From: Marcel Holtmann Date: Sun, 6 Jul 2014 12:11:16 +0200 Subject: [PATCH] Bluetooth: Clear HCI_RAW flag when controller becomes configured When an unconfigured controllers reaches the configured state, it is important to change the HCI_RAW flag. It indicates to userspace that the controller is fully operational. External configuration allows to bring the controller back into an unconfigured state. In that case make sure HCI_RAW flag is set again.
