Ah, I guess 50649ab14982a ("stmmac: drop driver from stmmac platform
code") was a over eager when removing stuff. I should have kept the
MODULE_* macro's as stmmac_platform can still be a module. I'll send
out a patch a bit later with a CC to you.

I'll look into this as well.

Thanks for reporting. If you could test patch I will send out soon
that would be of great help.
