From: stufever
Date: Wed Aug 10 2011 - 03:55:27 EST

From: Wang Shaoyan <wangshaoyan.pt@xxxxxxxxxx>

In commit 45eebda7, it add new function stac_vrefout_set, but it
is only used in code between CONFIG_SND_HDA_POWER_SAVE macro, so
add the macro to avoid such warning:

sound/pci/hda/patch_sigmatel.c:676:12: warning: 'stac_vrefout_set' defined but not used
