Linux-powered hybrid devices (Misc)

Hybrid devices for the character device:

To define a hybrid device:

struct misdevice{

int minor;  Why is there only a secondary device number because the hybrid device is a /////////////////////////linux system with the default main device number of 10 special character device.

const char *name;

const struct File_operation *fops;

struct List_head list;

struct device *parent;

struct device *this _device;

}

to Linux System Registration Hybrid device driver:
int Misc_register (struct misdevice *misc)// and functions: int cdev_add (struct Cdev///////////////////////////////////  *,dev_t,unsigned); same.

To uninstall a hybrid device:

int Misc_deregister (struct misdevice *misc)

Note: The initialization of a hybrid device does not use the function cdev_init (stuct cdev *,const struct file_operation *) to associate the device description structure with the set of device operation functions.
