Subject[PATCH 2.6] i2c-nforce2.c add support for nForce3 Pro 150 MCP
From
Hi Greg,

This patch applies to linux 2.6.10-RC1. I tried to follow the procedures
in Documentation/SubmittingPatches and I hope I got everything right.

Signed-off-by: Thomas Leibold <thomas@plx.com>

Thanks
Thomas

>>
>> I don't know if this works for other chips in the nForce3 family.

If you say yes to this option, support will be included for the Nvidia
Nforce2 family of mainboard I2C interfaces.
+ This driver also supports the nForce3 Pro 150 MCP.

This driver can also be built as a module. If so, the module
will be called i2c-nforce2.
