3.2-stable review patch. If anyone has any objections, please let me know.
------------------ From: Mark Brown <[email protected]> commit e7c248a049c2aac21bded0b0722caee6f0e57256 upstream. The jack detection on WM1811 is often required during system suspend, add it as another check when deciding if we should suspend.
