From cc78b44ba2231d6a92707407cd199b2e05fe3528 Mon Sep 17 00:00:00 2001 From: Marcel Holtmann Date: Sun, 6 Jul 2014 13:43:20 +0200 Subject: [PATCH] Bluetooth: Skip unconfigured init procedure for raw-only devices When the driver sets HCI_QUIRK_RAW_DEVICE, the controller will be set as unconfigured. However running the unconfigured init procecure is not useful since raw-only devices are not allowed to change its configuration. This change skips the init procedure and just allows user channel operation for this device.
