This adds support for the htu21 humidity and temperature sensor. To get it to work you have to do something like this: echo "htu21 0x40" >/sys/class/i2c-dev/i2c-1/device/new_device for example by adding it to rc.local Compile tested on brcm2708 and I have used an earlier version of this patch for more than a year.
