Instead of having to define m88e6390_hwmon_probe() twice, I would just
make marvell_hwmon_probe() a stub when CONFIG_HWMON=n?

Yes, i could do that. But again, i'm just following the pattern from
the other two sensors.

Humm, actually, no. It makes it more complex. If marvell_hwmon_probe()
is a stub, and we keep m88e6390_hwmon_probe() as the real
implementation, it means we need m88e6390_hwmon_chip_info, so we can
pass it. Either i need a stub version of m88e6390_hwmon_chip_info, or
i just build all the hwmon code even when CONFIG_HWMON is
disabled. The compiler might be able to figure out it is all unused
and throw it away, but i doubt it.

Having m88e6390_hwmon_probe() a stub is much simpler.
