hwmon: (ds620) Fix handling of negative temperatures

2011-10-03T18:41:05+00:00

commit cc41d586e8b4d76164fe7731c1c49be6cc5fc7e6 upstream.

Signed (negative) temperatures were not handled correctly.

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: (asus_atk0110) Fix memory leak

2011-07-17T16:39:18+00:00

The object returned by atk_gitm is dynamically allocated and must be
freed.

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.

hwmon: (pmbus) Improve auto-detection of temperature status register

2011-07-10T15:54:29+00:00

It is possible that a PMBus device supports the READ_TEMPERATURE2 and/or
READ_TEMPERATURE3 registers but does not support READ_TEMPERATURE1.
Improve temperature status register detection to address this condition.

hwmon: (lm95241) Fix negative temperature results

2011-07-10T15:54:15+00:00

Negative temperatures were returned in degrees C instead of milli-Degrees C.
Also, negative temperatures were reported for remote temperature sensors even
if the chip was configured for positive-only results.

Fix by detecting temperature modes, and by treating negative temperatures
similar to positive temperatures, with appropriate sign extension.
