Hi Pradeep,
That redundancy is noted in the book's errata (the 'unconfirmed' section):

My doubt is
though we have used cdev_init(&dev->cdev, &scull_fops) to initiaize
the fops structure for our embedded cdev, why are we again setting the
dev->cdev.ops explicity again using
dev->cdev.ops = &scull_fops;
Isn't cdev_init() supposed to do the initialisation?
