[Greg Kroah-Hartman]

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

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

From: Laura Abbott <labbott@xxxxxxxxxxxxxxxxx>

commit d05ea7da0e8f6df3c62cfee75538f347cb3d89ef upstream.

Much like all the other Lenovo laptops, add a quirk to make
sound work with docking.
