    Subject[ALSA hda 3.4-rc] suspend2ram regression in snd_hda_intel
    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
