   4 Subject: ALSA: hda - Disable power-widget control for IDT 92HD83/93 as default
   5
   6 From: Charles Chin <Charles.Chin@idt.com>

   8 commit 35c11777b906042eca9e6f1c03e464726c7faa07 upstream.
   9
  10 The power-widget control in patch_stac92hd83xxx() never worked properly,
  11 thus it's safer to turn it off as default for now.
