/*

   This module connects the pvrusb2 driver to the I2C chip level
   driver which handles device video processing.  This interface is
   used internally by the driver; higher level code should only
   interact through the interface provided by pvrusb2-hdw.h.

   Since there are several possible choices of low level drivers, we
   go through a layer of indirection in an attempt to select the right
   choice.  This module implements that indirection.
