How are device numbers determined in Linux driver?
Linux systems have two ways of identifying device files: Major device numbers identify modules serving device files or groups of devices. Minor device numbers identify specific devices among a group of devices specified by a major device number. We can define these numbers in the driver code, or they can be allocated dynamically.
