* Drop HWMON from the dependency list of ABITUGURU3 and LM93: this is

* Make the Abit, Asus and FSC chip drivers depend on X86. These are
  custom chips which can only be found on their respective manufacturer's
  systems, and these manufacturers only do x86 hardware AFAIK.

b353a487b9 hwmon: (lm85) Use dynamic sysfs callbacks
This lets us get rid of macro-generated functions and shrinks the
driver size by about 10%. I used a new style suggested by Mark M.
Hoffman to retrieve the channel number. Instead of:

	struct sensor_device_attribute *sda = to_sensor_dev_attr(attr);
	int nr = sda->index;

I do:

	int nr = to_sensor_dev_attr(attr)->index;

This looks better, and even allows the compiler to do some minor
optimizations.

45fb366940 hwmon: add support for Fintek F71882FG and F71883FG
This is the second version of a new driver for the hardware monitoring features
of the Fintek F71882FG and F71883FG Super-I/O chips. This version has several
small fixes for flaws discovered during the review of the first version.

This version of the driver does not support the pwm part of these chips (yet).
I'll first design a sysfs api for this and post that for discussion, and then
implement pwm support as an incremental patch over this one.

This driver supports all sensors of this chip, except for the vid inputs. The
vid inputs are somewhat documented in the datasheet, but I know nothing about
vid/vrm stuff. Help with this would be much appreciated.

1855256c49 drivers/firmware: const-ify DMI API and internals
Three main sets of changes:

1) dmi_get_system_info() return value should have been marked const,
   since callers should not be changing that data.

2) const-ify DMI internals, since DMI firmware tables should,
   whenever possible, be marked const to ensure we never ever write to
   that data area.

3) const-ify DMI API, to enable marking tables const where possible
   in low-level drivers.

And if we're really lucky, this might enable some additional
optimizations on the part of the compiler.

The bulk of the changes are #2 and #3, which are interrelated.  #1 could
have been a separate patch, but it was so small compared to the others,
it was easier to roll it into this changeset.

Which regressed into:

Make sure you loaded all the kernel drivers you need.
Try sensors-detect to find out which these are.
zsh: 2701 exit 1     sensors

and dmesg contains:

i2c-adapter i2c-0: Unsupported chip (man_id=0x4D, chip_id=0x4D).

acf346a311 hwmon: fix lm78 detection regression
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.

* I have experimental evidence that the W83627EHG needs more than 1
second to refresh all the measured values. Increase the caching time to
1.5 second.
* When changing a fan clock divider, the corresponding fan speed
measurement register is no longer valid, until the next time the chip
will refresh it. One way to fix this is to pretend that the cache is
still valid for one more period (1.5 second.)

Fix a potential race condition when some hardware monitoring platform
drivers are being unloaded. I believe that the driver data pointer

a sysfs callback might attempt to dereference a NULL pointer. I'm not
sure exactly what the driver core protects drivers against, so let's
play it safe.

While we're here, clear the driver data pointer when probe fails, so
as to not leave an invalid pointer behind us.

7817a39e65 hwmon: Fault files naming convention
We have the following naming convention documented in
Documentation/hwmon/sysfs-interface for fault files:

in[0-*]_input_fault
fan[1-*]_input_fault
temp[1-*]_input_fault

Some drivers follow this convention (lm63, lm83, lm90, smsc47m192).
However some drivers omit the "input" part and create files named
fan1_fault (pc87427) or temp1_fault (dme1737). And the new "generic"
libsensors follows this second (non-standard) convention, so it fails
to report fault conditions for drivers which follow the standard.

We want a single naming scheme, and everyone seems to prefer the
shorter variant, so let's go for it.
