Actually the only reference I could find is in 3.3:

        If a kernel module is built from several source files, you specify
        that you want to build a module in the same way as above; however,
        kbuild needs to know which object files you want to build your
        module from, so you have to tell it by setting a $(<module_name>-y)
        variable.

See commit 4f8272802739f5c6ce6b0a548810a181d2f1b652 for reasoning behind
the change.

Thanks.
