Needs to be at least in the commit message.

Yeah, according to the above, you better elaborate what this module is
and why people would need it.
Also can be a good hint to add
default ARCH_MY_COOL_PLATFORM

What do you mean? You don't use data structures from that?
of_device_id or other ID structures are defined there. Your module
works without them?

So? How does this make it impossible to address my comment?
