Crap, there's a difference. For [un]register_chrdev() the chrdev
layer keeps track of cdev while using cdev_alloc/add/del() directly
requires the caller to keep track of the pointer. Also, it's a bit of
pain to open code the whole thing.

For now, it looks like adding the __ prefixed versions seems to be the
proper solution. It's strange to provide the helper interface only
for full minor acquisitions anyway. Let's do naming cleanup later.
How does that sound?

Thanks.
