[78/99] hwmon: (it87) Fix VID reading on IT8718F/IT8720F

[Greg KH]

2.6.31-stable review patch.  If anyone has any objections, please let us know.

------------------
From: Jean Delvare <khali@xxxxxxxxxxxx>

commit 371dc4a6d8c3c74a9a1c74b87c2affb3fcef6500 upstream.

Comparing apples to bananas doesn't seem right. Consistently use the
chips enum for chip type comparisons, to avoid such bugs in the
future.

The bug has been there since support for the IT8718F was added, so
VID never worked for this chip nor for the similar IT8720F.
