  29  * Changes:
  30  *
  31  *  2002.09.09  Takashi Iwai <tiwai@suse.de>
  32  *      split the code to several files.  each low-level routine
  33  *      is stored in the local file and called from registration
  34  *      function from card_info struct.
  35  *
  36  *  2002.11.26  James Stafford <jstafford@ampltd.com>
  37  *      Added support for VT1724 (Envy24HT)
  38  *      I have left out support for 176.4 and 192 KHz for the moment.
  39  *  I also haven't done anything with the internal S/PDIF transmitter or the MPU-401
  40  *
  41  *  2003.02.20  Taksahi Iwai <tiwai@suse.de>
  42  *      Split vt1724 part to an independent driver.
  43  *      The GPIO is accessed through the callback functions now.
  44  *
  45  * 2004.03.31 Doug McLain <nostar@comcast.net>
  46  *    Added support for Event Electronics EZ8 card to hoontech.c.
