From: Greg Kroah-Hartman
Date: Sun Apr 26 2015 - 09:54:59 EST


3.10-stable review patch. If anyone has any objections, please let me know.

------------------

From: Marcel Holtmann <marcel@xxxxxxxxxxxx>

commit 40df783d1ef1989ac454e3dfcda017270b8950e6 upstream.

Intel Bluetooth devices that boot up in bootloader mode can not
be used as generic HCI devices, but their HCI transport is still
valuable and so bring that up as raw-only devices.
