/*
* Purpose: Template for OSS modules under Linux
*
* This file is included by the low level driver modules when they are
* compiled in the target system. In this way this file can be modified
* for non-standard kernels by the customer. Compiling in the target is
* necessary because the driver/module framework of Linux cannot support
* binary drivers. Another reason is that the kbuild mechanism used to build
* kernel modules under Linux is not compatible with the way how the source
* code of OSS is organized.
