Manually fix up conflicts due to kmemcheck in mm/slab.c
The LIS302DL accelerometer chip has a 'click' feature which can be used to
detect sudden motion on any of the three axis. Configuration data is
passed via spi platform_data and no action is taken if that's not
specified, so it won't harm any existing platform.
To make the configuration effective, the IRQ lines need to be set up
appropriately. This patch also adds a way to do that from board support
code.
The DD_* definitions were factored out to an own enum because they are
specific to LIS3LV02D devices.

Now that there is no need to hookup on the open/close of the joystick,
it's possible to use the simplified interface input_polled_device, instead
of creating our own kthread.

After measurement on my laptop, it seems that turning off the device does
not bring any energy saving (within 0.1W precision). So let's keep the
device always on. It simplifies the code, and it avoids the problem of
reading a wrong value sometimes just after turning the device on.
Moreover, since commit ef2cfc790b had been
too zealous, the device was actually never turned off anyway. This patch
also restores the damages done by this commit concerning the
initialisation/poweroff.
Also do more clean up with the usage of the lis3_dev global variable.

While working on f71852fg support I noticed that the f8000 sysfs attr
table was missing entries for temp#_fault, which the f8000 does have and
which we were already reading.

We depend up on the pwm_enable register (0x96) not containing any reserved
settings in various places. We were already checking to make sure there
were no reserved settings in the register for the f71862fg, this patch adds
the same checking for the f8000, while at it it also moves the code to
a more apropriate place so we don't need to check if the fan/pwm part
of the IC is enabled twice.

Currently we are using separate per model sysfs attr for the 3th pwm, because
the 3th pwm of the f8000 only has automatic mode and not manual mode. Doing
things this way was getting in the way for adding f71858fg support, so this
patch makes the pwm attr identical for all models, and instead adds a check
to store_pwm_enable() disallowing setting the 3th pwm to manual mode
on a f8000 IC.

The MSI MS-7031 is based on an ATI IXP300 south bridge. On this south
bridge, accessible I/O ports must be enabled explicitly. Unfortunately
the BIOS forgets to enable access to the hardware monitoring chip I/O
ports, so hardware monitoring fails.
Add a quirk enabling access to the required ports (0x295-0x296). This
is exactly what MSI's own hardware monitoring application is doing, so
it has to be the right way.

Add support for the new incarnation of the Winbond/Nuvoton W83627DHG
chip known as W83627DHG-P. It is basically the same as the original
W83627DHG with an additional automatic can speed control mode (not
supported by the driver yet.)

This adds support for TI's TMP411 sensor chip.
Preliminary support were done by Gabriel Konat, Sander Leget and
Wouter Willems. The chip is compatible with TI's TMP401 sensor
chip. It has additional support for historical minimun/maximum
measurements.

This is a new hwmon driver for TI's TMP401 temperature sensor IC. This driver
was written on behalf of an embedded systems vendor under the
Linux driver project.
It has been tested using a TI TMP401 sample attached to a i2c-tiny-usb adapter.
Which was provided by Till Harbaum, many thanks to him for this!

Commit 360782dde0 (hwmon: (w83781d) Stop
abusing struct i2c_client for ISA devices) broke W83782D support for
devices connected on the ISA bus. You will hit a NULL pointer
dereference as soon as you read any device attribute. Other devices,
and W83782D devices on the SMBus, aren't affected.

Data sheet at:
http://www.sensirion.ch/en/pdf/product_information/Datasheet-humidity-sensor-SHT1x.pdf
These sensors communicate over a 2 wire bus running a device specific
protocol. The complexity of the driver is mainly due to handling the
substantial delays between requesting a reading and the device pulling the
data line low to indicate that the data is available. This is handled by
an interrupt that is disabled under all other conditions.
I wasn't terribly clear on the best way to handle this, so comments on
that aspect would be particularly welcome!
Interpretation of the temperature depends on knowing the supply voltage.
If configured in a board config as a regulator consumer this is obtained
from the regulator subsystem. If not it should be provided in the
platform data.
I've placed this driver in the hwmon subsystem as it is definitely a
device that may be used for hardware monitoring and with it's relatively
slow response times (up to 120 millisecs to get a reading) a caching
strategy certainly seems to make sense!
