Install from clean build fails: 'invalid argument' during install about lcdi2c HOT 1 OPEN

Hello, I didn't touch the code for a while and really not quite sure yet what's happening but no problem I can check it. Honestly, I didn't expect people will find this module usable, and maybe finally it's a good time to take the code and make it more robust.
However, I wouldn't like to keep hollow promises I'll do it today or next week.
BTW symptoms are very peculiar as not giving arguments should set them to the default. I also consider if removing default args wouldn't be better for the sake of code simplicity enforcing explicitness of module config.

Thank you for your feedback.
