hwmon: (w83627ehf) Fix negative 8-bit temperature values

2011-10-25T05:10:17+00:00

commit 133d324d82e144588939ad25b732b5b6c33b03d9 upstream.

Since 8-bit temperature values are now handled in 16-bit struct
members, values have to be cast to s8 for negative temperatures to be
properly handled. This is broken since kernel version 2.6.39
(commit bce26c58df86599c9570cee83eac58bdaae760e4.)

hwmon: (w83627ehf) Properly report thermal diode sensors

2011-10-25T05:10:14+00:00

commit bf164c58e58328c40ebc597a8ac00cc6840f9703 upstream.

The w83627ehf driver is improperly reporting thermal diode sensors as
type 2, instead of 3. This caused "sensors" and possibly other
monitoring tools to report these sensors as "transistor" instead of
"thermal diode".

Furthermore, diode subtype selection (CPU vs. external) is only
supported by the original W83627EHF/EHG. All later models only support
CPU diode type, and some (NCT6776F) don't even have the register in
question so we should avoid reading from it.

hwmon: (max16065) Fix current calculation

2011-10-03T18:40:12+00:00

commit ff71c182f461da5ae9d2d65f8a63f5a9193b9be1 upstream.

Current calculation is completely wrong. Add missing brackets to fix it.

hwmon: (ibmaem) add missing kfree

2011-08-17T17:55:53+00:00

commit 66a89b2164e2d30661edbd1953eacf0594d8203a upstream.

rs_resp is dynamically allocated in aem_read_sensor(), so it should be freed
before exiting in every case.  This collects the kfree and the return at
the end of the function.

hwmon: (max1111) Fix race condition causing NULL pointer exception

2011-07-17T16:39:19+00:00

spi_sync call uses its spi_message parameter to keep completion information,
using a drvdata structure is not thread-safe. Use a mutex to prevent
multiple access to shared driver data.

hwmon: (it87) Fix label group removal

2011-07-17T16:39:19+00:00

A copy-and-paste error caused it87_attributes_vid to be referenced
where it87_attributes_label should be. Thankfully the group is only
used for attribute removal, not attribute creation, so the effects of
this bug are limited, but let's fix it still.

hwmon: (adm1275) Fix coefficients per datasheet revision B

2011-07-15T15:09:40+00:00

Coefficients to convert chip register values to voltage/current have been
slightly changed in revision B of the chip datasheet. Update driver coefficients
to match the coefficients in the datasheet.

hwmon: (pmbus) Use long variables for register to data conversions

2011-07-12T13:45:45+00:00

Using integer variable types for register to data conversions can cause
overflows especially for power calculations, which are in microwatt.
Use long variables instead.
