Sure, it actually was something I introduced myself :-(. I initialized the
fan_ctl register with (read_value & 0x8f | 0x77) to enable the smart
guardian feature for all 3 fans. But the power supply fan does not support
pwm. It can only be operated in on/off mode, i.e. bit 0 must be clear. I
switched it back to the original (rv & 0x8f | 0x70 ) and everything is back
to working.

Here it comes.

- fix voltage scaling
- swap voltage limits
- use lower critical rather than upper hysteresis
for non-temperature sensors
- increase libsensors support to 20 voltage, 10 fan,
10 temperature sensors
Tickets 1406 and 1407.

detected at the same address, cause the driver to be told to
ignore this address. Untested.

Hi.
I am using lm_sensors in a slightly patched form.
The motherboard is Intel D845BGL, which features
SMSC LPC47M142 LPC Bus I/O controller.
If you look at the 47m10x and 47m14x datasheets,
you'll notice they have different Device ID's
(the former has 0x59, the latter 0x5F). As far
as the fan monitoring is concerned, they are
pretty much identical.
The 47M142 will be recognized with only some
trivial modifications to the code. I've attached
diffs for lm_sensors-2.7.0 and lm_sensors-2.8.0.
Best regards,
Kalev Soikonen

Thanks!
This patch fixes the various return values in the w83781d_detect()
error paths. It also cleans up some formatting here and there.
It should be applied on top of the previous one.
It works for me; same caveat as above w.r.t. ISA.
