Sorry, I sent the wrong patchset that didn't fix this point out.

I have received your point out and have sent an email with the content
to remove this line. But it may not have arrived yet...

The reason why "def_bool y" was set is that the wrong fix was left when
debugging. Also, I don't think it is necessary to set "default y".
This is also incorrect because it says "bool" Toshiba Visconti DWMAC
support "". I change it to trustate in the new patch.

And this driver is enabled when STMMAC_PLATFORM was Y. And STMMAC_PLATFORM
depends on STMMAC_ETH.
So I understand that STMMAC_ETH does not need to be dependents. Is this
understanding wrong?
