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.

<content type='text'>
The it87 driver is reporting -128 degrees C as +128 degrees C.
That's not a terribly likely temperature value but let's still
get it right, especially when it simplifies the code.

<title>hwmon: Check for ACPI resource conflicts</title>

Check for ACPI resource conflicts in hwmon drivers. I've included
all Super-I/O and PCI drivers.

I've voluntarily left out:
* Vendor-specific drivers: if they conflicted on any system, this would
  pretty much mean that they conflict on all systems, and we would know
  by now.
* Legacy ISA drivers (lm78 and w83781d): they only support chips found
  on old designs were ACPI either wasn't supported or didn't deal with
  thermal management.
* Drivers accessing the I/O resources indirectly (e.g. through SMBus):
  the checks are already done where they belong, i.e. in the bus drivers.

The it87 driver doesn't follow the standard sensor type values as
documented in Documentation/hwmon/sysfs-interface. It uses value 2 for
thermistors instead of value 4. This causes "sensors" to tell the user
that the chip is setup for a transistor while it is actually setup for
a thermistor.

Using value 4 for thermistors solves the problem. For compatibility
reasons, we still accept value 2 but emit a warning message so that
users update their configuration files.

<title>hwmon: (it87) Prevent power-off on Shuttle SN68PT</title>

On the Shuttle SN68PT, FAN_CTL2 is apparently not connected to a fan,
but to something else. One user has reported instant system power-off
when changing the PWM2 duty cycle, so we disable it.

I use the board name string as the trigger in case the same board is
ever used in other systems.

This closes lm-sensors ticket #2349:
pwmconfig causes a hard poweroff

The IT8712F v0.9.1 datasheet applies to revisions &gt;= 0x8 (J).
The driver was incorrectly attempting to enable 16-bit fan
readings on rev 0x7 (I) which led to incorrect RPM values.
