Generic I2C: fix various problems with this (now) unused driver
Explicit if SDA is input or output in static functions
Do not use logf() but return codes
Check for overflow when adding an interface
Indent on 4 spaces
Rewrite i2c_read_data() and i2c_write_data() using goto for error cases
Make subaddress optional (not sent if == -1)
