[PATCH] add function documentation for register_chrdev()

	return 0;

}

/**

 * register_chrdev() - Register a major number for character devices.

 * @major: major device number or 0 for dynamic allocation

 * @name: name of this range of devices

 * @fops: file operations associated with this devices

 *

 * If @major == 0 this functions will dynamically allocate a major and return

 * its number.

 *

 * If @major > 0 this function will attempt to reserve a device with the given

 * major number and will return zero on success.

 *

 * Returns a -ve errno on failure.

 *

 * The name of this device has nothing to do with the name of the device in

 * /dev. It only helps to keep track of the different owners of devices. If

 * your module name has only one type of devices it's ok to use e.g. the name

 * of the module here.

 *

 * This function registers a range of 256 minor numbers. The first minor number

 * is 0.
