hwmon: (sht15) Fix integer overflow in humidity calculation

2011-03-23T20:04:16+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

2011-03-13T14:42:52+00:00

This avoids a possible race leading to trying to dereference NULL.

hwmon: (lm85) extend to support EMC6D103 chips

2011-02-19T01:43:36+00:00

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.

Add the PCI ID to support the internal temperature sensor of the
AMD "Llano" and "Brazos" processor families.

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

2011-02-16T16:18:33+00:00

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

2011-02-16T16:18:32+00:00

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.

type for strict_strtoul().
