/*
 * foodev.c - simple illustration of device node creation in driverfs.
 *
 * Copyright (c) 2002 Patrick Mochel
 *
 * This is simple and stupid. We declare a platform device, register it
 * with the system, then create a device node for it.
 * The major/minor used is the char misc device, and the first free minor
 * (right after the mk712 touchscreen; stupid mk712).
 *
 * This is very buggy, but it's not meant to be perfect. We should check
 * the return of the registration and creation functions. 
 * And, the module can be unloaded while there are still references to 
 * the device. Oh well..
 * 
 * Also, the device has no parent or bus. Don't do that. Ever. I wrote 
 * the API, so I'm special. ;)
 *
 * Compiled with:

CFLAGS = -Wall -O2 -fomit-frame-pointer -DMODULE -D__KERNEL__
