title: where do char device appear after cdev_add() registers successfully with major on 117.
body: <p>I have written basic char driver.</p>
  
  <p>Registration of char device with kernel has been done using cdev_alloc, cdev_init, cdev_add.
  Major = 117, Minor = 1.</p>
  
  <p>cdev_add function retrun success. 
  I am trying to check whether char device created or not.
  I dont find any device under /dev/ or /dev/char with major no 117.</p>
  
  <p>register_chrdev is not going to be use in the latest kernel, where we give NAME.
  but cdev_add perform char device registration with kernel using major number only.</p>
  
  <p>I am confused with the latest kernel behavior.</p>
  
  <p>Do i need to use register_chrdev along with cdev_add ?
  or
  Do i need to use mknod commad to showup device in /dev/ ?</p>
  
  <p>Thank you.</p>
