commit 60f2208699ec08ff9fdf1f97639a661a92a18f1c upstream.
The ds4424_get_value function takes channel number as it's 3rd
argument and translates it internally into I2C address using
DS4424_DAC_ADDR macro. The caller ds4424_verify_chip was passing an
already translated I2C address as its last argument.
