       register_sound_dsp - register a DSP device


       int register_sound_dsp  (struct file_operations * fops, int dev);


       fops   File operations for the driver

       dev    Unit number to allocate


       Allocate a DSP device. Unit is the number of the DSP requested. Pass -1
       to request the next free DSP unit. On success the allocated  number  is
       returned, on failure a negative error code is returned.

       This  function allocates both the audio and dsp device entries together
       and will always allocate them as a matching pair - eg dsp3/audio3
