      ALSA: take tu->qlock with irqs disabled · bfe70783
      Dan Carpenter authored
      
      
      We should disable irqs when we take the tu->qlock because it is used in
      the irq handler.  The only place that doesn't is
      snd_timer_user_ccallback().  Most of the time snd_timer_user_ccallback()
      is called with interrupts disabled but the the first ti->ccallback()
      call in snd_timer_notify1() has interrupts enabled.
      
      This was caught by lockdep which generates the following message:

      ALSA: hda - Fix resume from StR of HP 2510p with docking-station · b7d2526f
      Takashi Iwai authored
      When HP laptop with AD1981 codec is suspended and the docking-station
      is connected before the resume, the outputs get confused, and wrongly
      routed still to the speaker.  This is because of a change in 2.6.34-rc1

          ALSA: hda: Add powerdown for Analog Devices HDA codecs
      
      The problem was the added resume callback that doesn't consider the
      modified init hook.  The fix is simply remove the resume callback here
      and make the resume normally.  This doesn't change any behavior intended
      in the commit above (for shutting down the sound at suspend) but only
      fixes the resume.
