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.
MAX6646, MAX6647, MAX6648, MAX6649, MAX6657, MAX6658, MAX6659,
MAX6680, MAX6681 and MAX6692 sensor chips.
This driver can also be built as a module. If so, the module
will be called lm90.
