[PATCH] hwmon: (lm90) Add support for ADT7461A and NCT1008

From: Guenter Roeck
Date: Wed Apr 06 2011 - 11:30:22 EST


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.
