  2. slides/kernel-frameworks: add example of dev_get_drvdata 

    In the "specific struct has a reference to struct device" case, the
private structure is typically found through dev_get_drvdata(). Add an
example of that.

Of course, many frameworks have their own "private" pointer because they
already use drvdata, but explaining that as well would lead us too far.
