hwmon: (sht15) Check return value of regulator_enable()

2013-03-20T15:03:22+00:00

commit 3e78080f81481aa8340374d5a37ae033c1cf4272 upstream.

enable the supply and error out if we can't.

[bwh: Backported to 3.2: driver does not use the devm API to manage
 memory, so goto err_free_data rather than returning on error]

2011-05-19T15:19:36+00:00

The sht15 sensor allows validating exchanges to and from the device
using a crc8 function. An utility function to reverse a byte has also
been added.

hwmon: (sht15) Fix integer overflow in humidity calculation

2011-03-21T16:59:35+00:00

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.
