2 | * | |
3 | * 2002/06/30 Karsten Wiese: | |
4 | * removed kernel-version dependencies. | |
5 | * ripped from linux kernel 2.4.18 (OSS Implementation) by me. | |
6 | * In the OSS Version, this file is compiled to a separate MODULE, | |
7 | * that is used by the pinnacle and the classic driver. | |
8 | * since there is no classic driver for alsa yet (i dont have a classic | |
9 | * & writing one blindfold is difficult) this file's object is statically | |
10 | * linked into the pinnacle-driver-module for now. look for the string | |
11 | * "uncomment this to make this a module again" | |
12 | * to do guess what. | |
13 | * | |
14 | * the following is a copy of the 2.4.18 OSS FREE file-heading comment: | |
15 | * | |
16 | * msnd.c - Driver Base | |
17 | * | |
18 | * Turtle Beach MultiSound Sound Card Driver for Linux | |
