hwmon: (lm78) Add missing __devexit_p()

2009-06-15T16:40:06+00:00

commit 39d8bbedb9571a89d638f5b05358f26ab503d7a6 upstream.

The remove function uses __devexit, so the .remove assignment needs
__devexit_p() to fix a build error with hotplug disabled.

hwmon: (w83781d) Fix W83782D support (NULL pointer dereference)

2009-05-18T23:34:40+00:00

Commit 848ddf116b3d1711c956fac8627be12dfe8d736f upstream

Commit 360782dde00a2e6e7d9fd57535f90934707ab8a8 (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.

hwmon: (f75375s) Remove unnecessary and confusing initialization

2009-03-12T12:36:39+00:00

f75375_probe calls i2c_get_clientdata to initialize the data pointer,
but there isn't yet any client data to get, and the value is never
used before the variable is assigned a new value seven lines later.

The call doesn't hurt anything and wastes only a couple of cycles.
The reason to fix it is because this module serves as an example to
hackers writing new hwmon drivers, and this part of the example is
confusing.

hwmon: (it87) Properly decode -128 degrees C temperature

2009-03-12T12:36:39+00:00

The it87 driver is reporting -128 degrees C as +128 degrees C.
That's not a terribly likely temperature value but let's still
get it right, especially when it simplifies the code.

handling code in a clearer way.

lm85: add VRM10 support for adt7468 chip

2009-03-10T22:55:10+00:00

The adt7468 chip supports VRM10 sensors just like the adt7463; add a
missing check for it.

lm85: fix the version check that broke adt7468 probing

2009-03-10T22:55:10+00:00

The verstep check in the lm85 driver fails because the upper nibble of
the version register is 0x7, not 0x6, on the adt7468 chip.  Probing of
all adt7468s was broken by 69fc1feba2d5856ff74dedb6ae9d8c490210825c
("hwmon: (lm85) Rework the device detection"), and this patch fixes
that.  Also add in a missing i2c_device_id that accidentally got dropped
from the original patch.

lis3lv02d: add axes knowledge of HP Pavilion dv5 models

2009-02-18T23:37:54+00:00

Add support for HP Pavilion dv5.

Since Intel-based models have an inverted x axis, while AMD-based models
have an inverted y axis, we introduce a new macro that special-cases axis
orientation based on two DMI entries: HP dv5 axis configuration is then
based on both the PRODUCT and BOARD name.

lis3lv02d: support both one- and two-byte sensors

2009-02-18T23:37:54+00:00

Sensors responding with 0x3B to WHO_AM_I only have one data register per
direction, thus returning a signed byte from the position which is
occupied by the MSB in sensors responding with 0x3A.

Since multiple sensors share the reply to WHO_AM_I, we rename the defines
to better indicate what they identify (family of single and double
precision sensors).

We support both kind of sensors by checking for the sensor type on init
and defining appropriate data-access routines and sensor limits (for the
joystick) depending on what we find.
