Subject: lm90: support the MAX6648/6692 chips
From: "Darrick J. Wong" <djwong@xxxxxxxxxx>
The max6648 chip has nearly the same register set as the 6657 and seems to
have a working manufacturer/chip id so we can detect it. This patch adds
support for it. Tested on a Nvidia Quadro FX 1500 card.

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