This is expected to be good, because we tested with the "emulator" for the chip.
If you want to try that out:

http://assembler.cz/download/w83793/i2c-stub.c

You need to replace original i2c-stub in kernel/driver/i2c/busses and of course
choose it in menuconfig. When inserted it will just create a fake i2c bus with
fake chip on address 0x2f. Then if the module w83793 is loaded it will find this
chip and use it. The i2c-stub fakes the chip registers, so the reads from the
chip are exactly the same as from real chip - but they dont change. The writes
work too, because the modified value is stored in fake chip register.

We tried that when I was done with modifications of the drivers, so we at least
knew that this basic test would pass ;)

> If you have any idea that wants to be tested on w83793, feel free to contact us.

I think better would be to test setting of limits of voltages, fans. The a bit
of trip points. So generally the writes to the chip.
