PATCH: hwmon-lm78-detect-isa-with-chipid-0x20.patch

Mark,

Here is a small but important bugfix to the lm78 driver. I found out about this
problem because a Fedora user filed a bug that the lm78 driver no longer worked
on his system: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=249428

The problem is that sometime ago the isa lm78 detection was made more stringent
and this new code now checks the chip-id, but does not accept a chip-id of 20h,
however a chip-id of 20h is valid, and is excepted in the main probe function
of the driver, see line 551. This fixed also makes the isa detection code
accept the chip-id of 0x20 fixing this issue.

Please include this in the next batch to be send to Linus so that it will get 
into 2.6.23, this is a regression rendering the lm78 driver not working in 
certain cases.

Regards,

Hans
