[lm-sensors] Support for SMBus based GMT G781 and G7811 temperature sensors.

[Mike Gorchak]

Hello, Guenter!

 GR>>> never mind; no idea if G7811 ever really existed. I found version 1.3
 GR>>> of the datasheet which describes both G781 and G781-1. Can you test
 GR>>> the driver and sensors-detect if I send you a pointer to the code ?

 ??>> Let me explain what I did. I added support for ACPI SMBus connected to
 ??>> Embedded Controller to the lm-sensors (for a netbook without proper
 ??>> ACPI support). There are two G781 sensors connected to this bus, one

 ??>> 0x4D address.

 GR> Hi Mike,
 GR> can you send me the output of i2cdump for both chips ?

Of course, but output is produced by another utility with similair behavior.
