 This driver implements support for the hardware monitoring capabilities of the
 SMSC DME1737 and Asus A8000 (which are the same), SMSC SCH5027, SCH311x,
 and SCH5127 Super-I/O chips. These chips feature monitoring of 3 temp sensors
-temp[1-3] (2 remote diodes and 1 internal), 7 voltages in[0-6] (6 external and
+temp[1-3] (2 remote diodes and 1 internal), 8 voltages in[0-7] (7 external and
 1 internal) and up to 6 fan speeds fan[1-6]. Additionally, the chips implement
 up to 5 PWM outputs pwm[1-3,5-6] for controlling fan speeds both manually and
 automatically.
