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