Subject[07/63] ALSA: hda - VIA: Fix VT1708 cant build up Headphone control issue
2.6.38-stable review patch.  If anyone has any objections, please let us know.

------------------
From: Lydia Wang <lydiawang@viatech.com.cn>

commit ee3c35c0827de02de414d08b2ddcbb910c2263ab upstream.

Since VT1708 didn't support the control of getting connection number,
building of headphone control will fail in via_hp_build() function.
