hwmon: (sht15) Fix integer overflow in humidity calculation

2011-03-23T19:50:46+00:00

commit ccd32e735de7a941906e093f8dca924bb05c5794 upstream. An integer overflow occurs in the calculation of RHlinear when the relative humidity is greater than around 30%. The consequence is a subtle (but noticeable) error in the resulting humidity measurement.

hwmon/f71882fg: Set platform drvdata to NULL later

2011-03-23T19:49:50+00:00

commit d9ebaa45472c92704f4814682eec21455edcfa1f upstream. This avoids a possible race leading to trying to dereference NULL. Signed-off-by: Hans de Goede Acked-by: Jean Delvare Signed-off-by: Guenter Roeck Signed-off-by: Greg Kroah-Hartman

hwmon: (jc42) do not allow writing to locked registers

2011-02-24T22:54:36+00:00

commit 2c6315da6a1657a49e03970a4084dc3d1958ad70 upstream. On systems where the temperature sensor is actually used, the BIOS is likely to have locked the alarm registers. In that case, all writes through the corresponding sysfs files would be silently ignored. To prevent this, detect the locks and make the affected sysfs files read-only.

hwmon: (jc42) more helpful documentation

2011-02-24T22:54:36+00:00

commit d5622f5b6c4671d1588ccc9056705366d4eb312a upstream. The documentation lists standard numbers and chip names in excruciating detail, but that's all it does. To help mere mortals in deciding whether to enable this driver, mention what this sensor is for and in which systems it might be found. Also add a link to the actual JC 42.4 specification.

hwmon: (jc42) fix type mismatch

2011-02-24T22:54:35+00:00

commit e866729605a43a739fc56023a8530b07a93d3458 upstream. In set_temp_crit_hyst(), make the variable 'val' have the correct type for strict_strtoul(). Signed-off-by: Clemens Ladisch Signed-off-by: Guenter Roeck Signed-off-by: Greg Kroah-Hartman

hwmon: (k10temp) add support for AMD Family 12h/14h CPUs

2011-02-24T22:54:35+00:00

commit aa4790a6287818078ca968164a5f0d0870326602 upstream. Add the PCI ID to support the internal temperature sensor of the AMD "Llano" and "Brazos" processor families. Signed-off-by: Clemens Ladisch Signed-off-by: Guenter Roeck Signed-off-by: Greg Kroah-Hartman

hwmon: (lm85) extend to support EMC6D103 chips

2011-02-24T22:54:34+00:00

commit f065a93e168299569078bc6f52128b57f602fff3 upstream. The interface is identical EMC6D102, so all that needs to be added are some definitions and their uses. Registers apparently missing in EMC6D103S/EMC6D103:A2 compared to EMC6D103:A0, EMC6D103:A1, and EMC6D102 (according to the data sheets), but used unconditionally in the driver: 62[5:7], 6D[0:7], and 6E[0:7]. For that reason, EMC6D103S chips don't get enabled for the time being.

hwmon: (lm63) Consider LM64 temperature offset

2011-02-17T23:14:09+00:00

commit 2778fb13ba0fed1b3e4a040e71f7881d399610a3 upstream. LM64 has 16 degrees Celsius temperature offset on all remote sensor registers. This was not considered When LM64 support was added to lm63.c. Signed-off-by: Dirk Eibach Signed-off-by: Guenter Roeck Signed-off-by: Greg Kroah-Hartman

hwmon: (applesmc) Relax the severity of device init failure

2011-02-17T23:13:37+00:00

commit 2344cd0c2e9ea8f3037be11fb997ddbeda0237ca upstream. The device init is used to reset the accelerometer. Failure to reset is not severe enough to stop loading the module or to resume from hibernation. This patch relaxes failure to a warning and drops output in case of success.

hwmon: (applesmc) Add MacBookAir3,1(3,2) support

commit 132af03233b493101a53010383b5abb5b9ff1e51 upstream. This patch add support for the MacBookAir3,1 and MacBookAir3,2 to the applesmc driver.
