    ALSA: hda - Clear the leftover component assignment at snd_hdac_i915_exit()

    The commit [d745f5e7b8b2: ALSA: hda - Add the pin / port mapping on
    Intel ILK and VLV] introduced a WARN_ON() to check the pointer for
    avoiding the double initializations.  But hdac_acomp pointer wasn't
    cleared at snd_hdac_i915_exit(), thus after reloading the HD-audio
    driver, it may result in the false positive warning.  This patch makes
    sure to clear the leftover pointer at exit.
