The driver uses be16_to_cpu and cpu_to_be16 to convert data in SMBus word
operations from chip to host byte order. However, the data passed from and to
the SMBus word API functions is in host byte order, not in chip byte order.
Conversion should therefore use swab16 instead of be16 to change the byte order.
Replace driver internal word conversion functions with SMBus API functions to
solve the problem.

hwmon: struct x86_cpu_id arrays can be __initconst
The behavior of the SMC has changed several times over the years,
causing read failures in the driver. It seems the problem can be
explained by a shift in SMC speed combined with improper action on
status codes.
We should first wait for the SMC to settle, which was the most
frequent response on the old slow machines. Then, if the SMC is busy,
we need to try again later by resending the command. This was the most
likely response until 2012. Now, with a shorter wait time, we are
again most likely to poll while the SMC is settling, and as a result
we see high failure rates on many old and new models.
With the distinction between busy and failure, we can also wait longer
before retrying, without sacrificing speed. This seems to bring
failures down to virtually zero on all models.

There are many userland reports of sensors with unreasonably small and
large temperatures. There seem to be several reasons for this:
Firstly, the major sensor type (sp78) is actually a signed number.
This explains why some sensors show very small or large values - they
are in fact all small, but of different sign.
Secondly, the other sensor type (1-hex) is not properly understood; it
may be that it is not a temperature after all.
Thirdly, some sensors are differential in nature, showing changes over
time rather than absolute numbers. This explains why those values are
small and of varying sign.
This patch interprets the sp78 type as signed short, but keeps the
original scaling. For other types, -EINVAL is returned, since the
nature of those sensors is unknown.

The 2012 series of MacBooks have a faster SMC, and the current driver
timings do not work at all. Tests show that decreasing the minimum
wait time, from 64 us to 16 us, works well. Since this is still larger
than the original minimum of 10 us used before 2008, there is nothing
inherently problematic with changing it. The fail frequency on older
machines seems to increase slightly, but not enough to be noticeable.

An unsigned value can not be smaller than 0. Remove the check for it.
Use DIV_ROUND_CLOSEST for divide operations converting milli-degrees C into
degrees C. Limit maximum accepted trip point temperature to INT_MAX.
This patch fixes Coverity #115214: Unsigned compared against 0

This is a new driver for the Honeywell Humidicon HIH-6130/HIH-6131 humidity sensor.
The driver is based on the existing Sensiron sht21 driver with the necessary changes
to the probe, update_measurements and conversion functions necessary to use the
Honeywell sensors.
There's no difference between the 6130 & 6131 other than the 6131 having an external
condensation filter attached.

Fix Coverity warning: Calling strncpy with a maximum size argument of 20 bytes
on destination array "data->name" of size 20 bytes might leave the destination
string unterminated.
Fix by replacing strncpy() with strlcpy() and by using sizeof() to determine
the maximum string length.
