I know I wasn't the best example here. But if you continue to work on
that one, if would be nice if you could replace all the pr_err() here
with a dev_err() (or so) so it is bound to an actual device and the
reader can actually pin point the message to the actually device/
subsystem. I'm not sure if we lack a device or I was extremely lazy.
Again, not something you need change now.
