Looking closer into the SHT85 datasheet, the sensor chip is actually a SHT35.
Given that, disabling limit attributes and alarms is neither necessary
nor acceptable. It isn't even necessary to add "sht85" to the device ID
table; sht3x works just fine. I don't mind if it is added, but it does
not need a new chip ID (at least until/unless interrupt support is added
to the driver).
Thanks,
Guenter
