This caused a surprising number of kernel file rebuilds for me, and

It turns out that the above is indirectly included from a _lot_ of
code device header files.
The reason seems to be the various 'struct *_device_id' declarations,
that then all the different header files want.
So a tiny change in an oddball header file causes a lot of recompiles.
Oh well. I don't know if there is anything to be done, but I did react
to how some surprising changes cause a lot of build activity, and it's
not always obvious.
