This is explained much later in the training, but I think it's important to mention this early on already. Otherwise, things that are explained immediately afterwards don't make much sense (e.g. the fact that you have a struct device twice: once for the bus and once for the functional framewoek).
While using the bootlin materials for an internal training, there are a few improvements I made (at least, I consider them improvments myself). Since you probably don't agree with all of them, I'm making separate PRs for each. Feel free to close the PR if you disagree with the idea.
