3  * Linux multisound pinnacle/fiji driver for ALSA.
4  *
5  * 2002/06/30 Karsten Wiese:
6  *      for now this is only used to build a pinnacle / fiji driver.
7  *      the OSS parent of this code is designed to also support
8  *      the multisound classic via the file msnd_classic.c.
9  *      to make it easier for some brave heart to implemt classic
10  *      support in alsa, i left all the MSND_CLASSIC tokens in this file.
11  *      but for now this untested & undone.

14  * ripped from linux kernel 2.4.18 by Karsten Wiese.
