The smatch static code analyzer complains: drivers/hwmon/w83627ehf.c:911 w83627ehf_update_device() error: buffer overflow 'W83627EHF_REG_TEMP_OFFSET' 3 <= 8 drivers/hwmon/w83627ehf.c:909 w83627ehf_update_device() error: buffer overflow 'data->temp_offset' 3 <= 8 drivers/hwmon/w83627ehf.c:2672 w83627ehf_resume() error: buffer overflow 'W83627EHF_REG_TEMP_OFFSET' 3 <= 8 drivers/hwmon/w83627ehf.c:2673 w83627ehf_resume() error: buffer overflow 'data->temp_offset' 3 <= 8 A deeper analysis of the code shows that these are false positives, as only the lower 3 bits of data->have_temp_offset can be set so the write is never attempted with i >= 3. However this shows that the code isn't very robust and future changes could easily introduce a buffer overflow. So let's add a safety check to prevent that and make smatch happy.

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.

2011-03-14hwmon: (w83627ehf) Store rpm instead of raw fan speed dataGuenter Roeck1-18/+9
Since the fan speed value can be above 0xff, we can no longer use that value to determine if the fan speed reading is valid. This makes it difficult to manipulate the stored fan speed register value. If we store rpm instead of the fan speed register value, we do not need to correct it if the fan divisor value is changed, and the above mentioned problem no longer exists.

2011-03-14hwmon: (w83627ehf) Use 16 bit fan count registers if supportedGuenter Roeck1-27/+59
Some of the chips supported by this driver have 13 bit or 16 bit fan count registers. This patch improves support for those registers, specifically for NCT6775F. With the changes in this patch, fan speed is reported correctly even if the fan divider is set to a low value, which results in a fan speed reading above 0xff. With this patch, the width of fan count registers is no longer used to determine if the chip has fan divider register(s) or not. A dedicated flag is used instead to determine if this is the case.
