This patch adds support for ADT7461A and NCT1008 to the lm90 driver.
Both chips have identical functionality and report the same manufacturing ID
and device ID values.

Would this be a candidate for 2.6.39 and possibly -stable ?

This driver can also be built as a module. If so, the module
will be called lm90.
