Hello, I'm seeing the following compiler warning, does it look useful? I'm doing a v3.10-rc5 x86-64 build.

It's because CONFIG_ISAPNP isn't set (it's optional). You can add ifdef to hide the warning, but it makes the code uglier, OTOH.
Since this driver is a legacy one and almost no one uses it, better to save your time for more useful things, I'd say :)
thanks,
Takashi
