* hwmon: (it87) Fix label group removalJean Delvare2011-07-17
| | | | | | | | | | | 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.

| | | | | | | | | | | | The LM95241 driver accepts every chip ID equal to or larger than 0xA4 as its own, and other chips such as LM95245 use chip IDs in the accepted ID range.

* hwmon: (coretemp) Add comments describing the handling of HT CPUsGuenter Roeck2011-05-24
| | | | | | | | | | | | | | | | | | | | The coretemp driver provides a single set of device attributes for each physical core of a HT CPU to avoid duplicate sensors. This functionality was introduced with commit d883b9f09772 ("hwmon: (coretemp) Skip duplicate CPU entries"). Commit e40cc4bdfd4b ("x86/hwmon: register alternate sibling upon CPU removal") extends this functionality to register the HT sibling of a CPU which is taken offline, to ensure that sensor attributes are provided if at least one HT sibling of a core is online. Add comments into the code describing the functionality in some more detail.

* hwmon: (coretemp) Fix compile error if CONFIG_SMP is not definedGuenter Roeck2011-05-23
| | | | | | | | | | | | | cpu_sibling_mask() is not defined unless CONFIG_SMP is defined, so it must not be used directly in the code without ifdef protection. To solve the problem and avoid ifdefs in the code, define for_each_sibling() and use it instead.

* hwmon: Remove pkgtemp driverGuenter Roeck2011-05-21
