[PATCH] Bluetooth: btusb: Modify entry to support misc devices with BT interface

From: Xi Ruoyao
Date: Mon Jun 22 2015 - 11:29:37 EST

In the USB device table in btusb driver, the code specify a generic Bluetooth
device by matching Device Descriptor. However, some devices with BT interface
are classified as "Miscellaneous Device" and have different Device Descriptor,
such as Realtek RTL8723AU. Then btusb wouldn't probe them.

To resolve this, specify generic Bluetooth device in the USB device table by
matching Interface Descriptor, to probe all devices with Bluetooth interface
including these "Miscellaneous" ones.
