Subject: [195/262] ALSA: hda - Disable power-widget control for IDT 92HD83/93 as default

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

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

From: Charles Chin <Charles.Chin@....com>

commit 35c11777b906042eca9e6f1c03e464726c7faa07 upstream.

The power-widget control in patch_stac92hd83xxx() never worked properly,
thus it's safer to turn it off as default for now.
