  23    This module connects the pvrusb2 driver to the I2C chip level
  24    driver which performs analog -> digital audio conversion for
  25    external audio inputs.  This interface is used internally by the
  26    driver; higher level code should only interact through the
  27    interface provided by pvrusb2-hdw.h.
