It is not a sysbus device and not a module.

If it still compiles and links, it must get it via some other header.

Yes: wdt_diag288.c -> include/hw/watchdog/wdt_diag288.h ->
include/qom/object.h -> include/qemu/module.h

So what's now our expectation here? Should every file that uses type_init()
also include module.h ? That's IMHO not very intuitive...
Or are we fine that type_init() is provided by qom/object.h which needs to
be pulled in by every device sooner or later anyway?

I think it's okay to rely on indirect inclusion.

So, what's the final verdict? Maybe just tweak the description?
"Neither sysbus.h nor module.h are required to compile this file.
diag288 is not a sysbus device, and module.h (for type_init) is
included eventually through qom/object.h."

Yes, I think that's the way to go. Could you update the description when
picking up the patch, or shall I send a v2?

No need for a v2, I queued it to s390-next with an updated description.
