3.13.11-ckt18 -stable review patch.  If anyone has any objections, please let me know.


From: Hui Wang <hui.wang at canonical.com>

commit af95b41426e0b58279f8ff0ebe420df49a4e96b8 upstream.

We have a HP machine which use the codec node 0x17 connecting the
internal speaker, and from the node capability, we saw the EAPD,
if we don't set the EAPD on for this node, the internal speaker
can't output any sound.
