Hi,
I got one nitpick/question about this, see below

Are you sure that superio_exit() should be skipped (with goto exit) in
case it87_gpio_set() fails?
After all, superio_enter() above (not visible here) succeeded,
only the it87_gpio_set() call failed.

Of course this is kinda academic because currently it87_gpio_set()
always returns 0, but if it ever doesn't, this might become a bug?

Cheers,
Daniel
