ldd3: Linux Device Drivers 3 examples updated to work with recent kernels

About
-----

Linux Device Drivers 3 (http://lwn.net/Kernel/LDD3/) book is now a few years
old and most of the example drivers do not compile in recent kernels.

This project aims to keep LDD3 example drivers up-to-date with recent kernels.

The original code can be found at: http://examples.oreilly.com/9780596005900/

Compiling
----------

The example drivers should compile against latest Linus Torvalds kernel tree:
* git://git.kernel.org/pub/scm/linux/kernel/git/sfr/linux-next.git

To compile the drivers against a specific tree (for example Linus tree):

$ git clone git://github.com/martinezjavier/ldd3.git
$ git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
$ export KERNELDIR=/path/to/linux
$ cd ldd3
$ make
