I had to fix up this patch because:

obj-$(CONFIG_RAVB) += ravb_main.o ravb_ptp.o

Doesn't do what you want it to for the modular case.

You instead need to say something like:

ravb-objs := ravb_main.o ravb_ptp.o

obj-$(CONFIG_RAVB) += ravb.o

and that's how I fixed up this commit before pushing it out.
