    ALSA: hda - Use own workqueue · 6acaed38
    Takashi Iwai authored
    snd-hda-intel driver used schedule_work() fot the delayed DMA pointer
    updates, but this has several potential problems:
    - it may block other eventsd works longer
    - it may deadlock when probing fails and flush_scheduled_work() is
      called during probe callback (as probe callback itself could be
      invoked from eventd)
    
    This patch adds an own workq for each driver instance to solve these
    problems.
