3.16.7-ckt6 -stable review patch. If anyone has any objections, please let me know.

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

From: Jochen Hein <jochen@xxxxxxxxxx>

commit 1d90d6d5522befa8efa1a7ea406be65cf865ded4 upstream.

Without this the aux port does not get detected, and consequently the touchpad
will not work.

With this patch the touchpad is detected:
