           If you say yes here you get support for National Semiconductor LM90,
           LM86, LM89 and LM99, Analog Devices ADM1032 and ADT7461, and Maxim
-          MAX6646, MAX6647, MAX6649, MAX6657, MAX6658, MAX6659, MAX6680 and
-          MAX6681 sensor chips.

+          MAX6680, MAX6681 and MAX6692 sensor chips.
 
           This driver can also be built as a module.  If so, the module
           will be called lm90.
