Mainline commit 785f857d1cb0856b612b46a0545b74aa2596e44a
("ALSA: hda - Set codec to D3 forcibly even if not used")
breaks sound for my notebook (thinkpad x220),
looks like codec cannot wake from power-save state after resume.
After reverting looks like all works fine.

how to reproduce:
* unplug the power cord (to enable hda power safe mode)
* play something and stop
* wait until the background noise disappears (codec went into power-save mode)
* suspend
* resume
* play something again and hear the silence
