2009-03-30hwmon: (ds1621) Clean up register accessJean Delvare
Fix a few oddities in how the ds1621 driver accesses the registers: * We don't need a wrapper to access the configuration register. * Check for error before calling swab16. Error checking isn't complete yet, but that's a start. * Device-specific read functions should never be called during detection, as by definition we don't know what device we are talking to at that point. * Likewise, don't assume that register reads succeed during detection.

2009-03-12hwmon: (f75375s) Remove unnecessary and confusing initializationAndrew Klossner
f75375_probe calls i2c_get_clientdata to initialize the data pointer, but there isn't yet any client data to get, and the value is never used before the variable is assigned a new value seven lines later. The call doesn't hurt anything and wastes only a couple of cycles. The reason to fix it is because this module serves as an example to hackers writing new hwmon drivers, and this part of the example is confusing.

2009-02-18lis3lv02d: support both one- and two-byte sensorsGiuseppe Bilotta
Sensors responding with 0x3B to WHO_AM_I only have one data register per direction, thus returning a signed byte from the position which is occupied by the MSB in sensors responding with 0x3A. Since multiple sensors share the reply to WHO_AM_I, we rename the defines to better indicate what they identify (family of single and double precision sensors). We support both kind of sensors by checking for the sensor type on init and defining appropriate data-access routines and sensor limits (for the joystick) depending on what we find.

However, they correspond to the same ACPI functionality, and so will always be used together, moreover as they share the same ACPI PNP alias, there is no other simple to allow to have same loaded at the same time if they are not in the same module.

2009-01-15hwmon: applesmc: fix light sensor readings on newer MacBooksAlex Murray
The light sensors ALV0 and ALV1 on newer MacBooks (early 2008 and later) changed to report 10 bytes instead the earlier 6, and the sensor encoding subsequently changed. As a result, the reported light sensors readings are much too low. Via experiments leading up to this patch, it seems only the ALV0 is reporting data, and the most useful value therein is a 10-bit big-endian value at offset 6. This suggests that a new protocol was added as a backward-compatible replacement on top of the old one. This patch makes applesmc report the improved light sensor reading for the new machines, on a scale in conformance with earlier ones.

2009-01-15hwmon: (abituguru3) Fix CONFIG_DMI=n fallback to probeAlistair John Strachan
When CONFIG_DMI is not enabled, dmi detection should flag that no board could be detected (err=1) rather than another error condition (err<0).

2009-01-15hwmon: (abituguru3) Match partial DMI board name stringsAlistair John Strachan
The switch-over to using DMI board strings to identify abituguru3 compatible mainboards works most of the time, but sometimes the vendor has substantially modified the board string between BIOS revisions. We have found that the vendor chipset identification string (provided in brackets) changes frequently and is of no use to us. The rest of the board string sometimes changes in subtle ways, e.g. whitespace or variations in capitalization. The new comparison code checks only a part of the supplied DMI board string, trimming the bracketed content, whitespace, and ignoring case as necessary. This fixes a bug where an IP35 Pro running an early BIOS would not be detected without the force=1 module parameter, and also speculatively fixes other similiar issues.

2009-01-15hwmon: (k8temp) Fix temperature reporting for (most) K8 RevG CPUsAndreas Herrmann
Current Temperature for K8 RevG desktop CPUs is a "normalized value" which can be below ambient temperature. As a consequence lots of RevG systems report temperatures like: $ sensors k8temp-pci-00c3 Adapter: PCI adapter Core0 Temp: +17 C Core0 Temp: +3 C Core1 Temp: +21 C Core1 Temp: +5 C being quite below ambient temperature.
