commit bfa02b0da66965caf46e441270af87edda4fea14 upstream. Commit 2265cef2 (hwmon: (w83627ehf) Properly report PECI and AMD-SI sensor types) results in kernel panic if data->temp_label was not initialized. The problem was found with chip W83627DHG-P. Add check if data->temp->label was set before use. Based on incomplete patch by Alexander Beregalov.

commit 2265cef2751b3441df91f85e0107f9f549e5b711 upstream. When temperature sources are PECI or AMD-SI agents, it makes no sense to report their type as diode or thermistor.

2011-11-11hwmon: (coretemp) Fix for non-SMP buildsJean Delvare
commit 2aba6cac2a84f3b80e11a680c34d55e7739b474d upstream. The definition of TO_ATTR_NO in the non-SMP case is wrong. As the SMP definition resolves to the correct value, just use this for both cases. Without this fix the temperature attributes are named temp0_* instead of temp2_*, so libsensors won't pick them. Broken since kernel 3.0.

2011-10-25hwmon: (w83627ehf) Fix negative 8-bit temperature valuesJean Delvare
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.)

2011-10-25hwmon: (w83627ehf) Properly report thermal diode sensorsJean Delvare
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.
