There are many devices for Linux. So there must be a way to treat them systematically when you know these devices. first find out what structure is used to describe the hybrid device in the Linux kernel code. The second is how to register. Is the

The Stack is one of the most fundamental data structures, which are based on the principle of last in first out (LIFO). The basic operations include Push (inserting an element onto the top position) and POP (deleting the top element). Now is
