Subject: [ 06/70] ALSA: hda - add dock support for Thinkpad X230 Tablet

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

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

From: David Henningsson <david.henningsson@...onical.com>

commit 108cc108a3bb42fe4705df1317ff98e1e29428a6 upstream.

Also add a model/fixup string "lenovo-dock", so that other Thinkpad
users will be able to test this fixup easily, to see if it enables
dock I/O for them as well.
