Subsystem: bluetooth drivers, the rest · Maintainers: Marcel Holtmann, Luiz Augusto von Dentz, Linus Torvalds

From: Techie Ernie <redacted>

Add USB ID 0489:e112 for the Realtek 8851BE Bluetooth adapter.
Without this entry, the device is not handled correctly by btusb.
Adding the ID enables proper Realtek initialization for Bluetooth to work on various motherboards using this Bluetooth adapter.

The device identifies as:
  Bus 001 Device XXX: ID 0489:e112 Foxconn / Hon Hai Bluetooth Radio

Tested on Realtek 8851BE.
