Most of the concepts from LDD3 are still valid, many of the details are
dead wrong.

Can't we make LDD4 a high level book, explcitly mentioning how people
should go about obtaining details? Like go ask on #kernelnewbies and the
sorts.

The thing I always tell #kernelnewbies people is to look at a related
driver (of course that kite doesn't always fly). Another good way to
learn stuff is to just read the implementation.

A 'trick' that is often useful is to look in git to see how something
was changed, provided you knew how to do it some time in the past.
