This week's driver porting article (below) discusses the class mechanism,
which is part of the device model. At this point, this series is nearing
completion. There will be an occasional new article, and the existing base
of articles (30 of them, now) will be updated as the kernel hackers do
their best to make them obsolete. But these articles will no longer appear
every week. Creating this series has been a lot of work, but also a lot of
fun; many thanks to all of you for your support and helpful comments.
