Writing the Device Configuration File
This driver requires a configuration file. The minimum information that a configuration file
must contain is the name of the device node and the name or
type of the device's parent. In this simple example, the node name
of the device is the same as the file name of the driver.
Create a file named dummy.conf in your working directory. Put the following
single line of information into dummy.conf:
name="dummy" parent="pseudo";
