I missed that one, sorry.

How about drivers/net/ethernet/toshiba/tc35815.c ? It now has an unused
variable due to e7f4dc3536a4, and it fails to build because of 7f854420fbfe.

Which leads to the question which of the other build failures due to
7f854420fbfe have been addressed already. In addition to the toshiba driver,
I see build failures in drivers/net/ethernet/ti/cpmac.c and possibly
drivers/staging/octeon/ethernet-rgmii.c (the error message is different,
so it may be something else).

I don't see patches for those, but I guess I must be blind, so I figure I
better ask before I send out mine.

Thanks,
Guenter
