This one is similar to kernel.h in that it's mostly a catch all header
that we prefer to replace if possible with more specific ones.

Now the driver might directly dereference a struct device, but if

Maybe it's something else.  As mentioned in previous review
providing that info under the --- in the patch can save time on
questions like this.
