Jekyll Lai 7a1b76f2a4 hwmon: (emc1403) Add EMC1423 support
EMC1423 uses the similar register and adds a hardware shutdown pin to
protect exceed temperature. This function is set by resistor; it's not
necessary to do anything in the driver except add the emc1423 pid of 0x23.

Jean Delvare 36c7fe133e hwmon: (w83793) Drop useless mutex
This is the same case as fschmd, from which the code was copied as far
as I can see. So the same clean-up applies:

The WDIOC_GETSUPPORT ioctl only needs a mutex because it operates on a
static variable. There is no good reason to keep this variable static,
so let's just make it non-static and drop the now useless mutex
altogether.

Jean Delvare f790674d3f hwmon: (via686a) Initialize fan_div values
Functions set_fan_min() and set_fan_div() assume that the fan_div
values have already been read from the register. The driver currently
doesn't initialize them at load time, they are only set when function
via686a_update_device() is called. This means that set_fan_min() and
set_fan_div() misbehave if, for example, "sensors -s" is called
before any monitoring application (e.g. "sensors") is has been run.

Fix the problem by always initializing the fan_div values at device
bind time.

Jean Delvare 014bcd28a0 hwmon: (w83795) Silent false warning from gcc
The code triggers a false warning with older versions of gcc:
w83795.c: In function 'w83795_update_device':
w83795.c:475: warning: 'lsb' may be used uninitialized in this function

I admit that the code is a little tricky, but I see no way to write it
differently without hurting performance. So let's just silent the
warning with a needless initialization.

Henrik Rydberg 9792dadfce hwmon: (applesmc) Dynamic creation of temperature files
The current driver creates temperature files based on a list
of temperature keys given per device. Apart from slow adaption
to new machine models, the number of sensors also depends on
the number of processors. This patch looks up the temperature

Henrik Rydberg 5874583d56 hwmon: (applesmc) Introduce a register lookup table
One main problem with the current driver is the inability to quickly
search for supported keys, resulting in detailed feature maps per
machine model which are cumbersome to maintain.

This patch adds a register lookup table, which enables binary search
for supported keys. The lookup also reduces the io frequency, so the
original mutex is replaced by locks around the actual io.
