[Mike Lothian <mike@fireburn.co.uk>]

Add the Kconfig entry, the Makefile rule and the MAINTAINERS record, so the
preceding commits become a module.

+	  Open in-kernel Rust driver for DisplayLink DL3 docks: the DL-3x00
+	  port replicators, the Dell Universal Dock D6000 and other DL-6xxx
+	  docks, and the DL-7400 quad-display docks. A dock is matched on its
+	  USB function rather than on a product id, and identified from the
+	  vendor descriptor it carries.
+
+	  It binds the dock over USB, runs the HDCP 2.2 control plane, mode-set
+	  and the Vino codec, and registers a DRM/KMS sink that scans out to the
+	  dock's video endpoints.
+
+	  To compile this as a module, choose M here: the module is called vino.

+	  The tests run when the driver is loaded, so this option is intended
+	  for driver development and test kernels rather than normal use.
+
