15  * Changes:
16  *
17  *  2002.09.09	Takashi Iwai <tiwai@suse.de>
18  *	split the code to several files.  each low-level routine
19  *	is stored in the local file and called from registration
20  *	function from card_info struct.
21  *
22  *  2002.11.26	James Stafford <jstafford@ampltd.com>
23  *	Added support for VT1724 (Envy24HT)
24  *	I have left out support for 176.4 and 192 KHz for the moment.
25  *  I also haven't done anything with the internal S/PDIF transmitter or the MPU-401
26  *
27  *  2003.02.20  Taksahi Iwai <tiwai@suse.de>
28  *	Split vt1724 part to an independent driver.
29  *	The GPIO is accessed through the callback functions now.
30  *
31  * 2004.03.31 Doug McLain <nostar@comcast.net>
32  *    Added support for Event Electronics EZ8 card to hoontech.c.
