need feedback on si700x usb driver

[Prashant Shah]

Hi,

I have been working on connecting a USB to I2C communication module
from Silicon Labs - Si700x.

It consists of a temperature and humidity sensor which connects
through I2C bus. Si700x is a evaluation module that converts the I2C
data to USB which is then sent to the PC. I need feedback on the
driver code which is uploaded on github.com.

Sensor -> I2C -> Si700x Evaluation Board (I2C to USB) -> USB -> PC

git repo : https://github.com/prashants/si700x

driver file : https://github.com/prashants/si700x/blob/master/si700x.c

Regards.
