Subject: [PATCH] ALSA: intel_hda - Add dock support for ThinkPad T460s

Hi!
The new ThinkPad T460s is the same way affected, as other current ThinkPads (e.G. X260) generations.
That means, you won't be able to get sound output, when using the Lenovo
CES 2013 docking station series (basic, pro, ultra).

It can be fixed the same way, as it was already done for X260,
as the T460s uses the same docking connector.
I am attaching a patch, which works for me.

Cheers
Conrad
