If he doesn't, then Corbet, Rubini & Kroah-Hartman certainly do....
The 3rd ed. of "Linux Device Drivers" is now online courtesy of LWN at
lwn.net/Kernel/LDD3/, and the example source code (including the odd
Makefile) is at http://examples.oreilly.com/linuxdrive3/examples.tar.gz
This is *the* book on the subject, and it's really good. If you get the
dead-tree version, make sure you check the errata page, though, because
there's a disconcerting (for an O'Reilly text) number of trivial
errors (e.g. while writing the book, they used "Chapter 1" instead of
"Chapter FIXME!" and missed it at link-time), and a few more serious ones.
