Hi! This seems like fairly straight forward cleanups/bugfixes. I don't have the hardware and found the issues by reading code while doing other things. So, it builds for me, but it's untested. 1/3 changes behavior on failure, but I think it's the right thing to do. If it isn't for some reason, then the current code is crap anyway, because as-is it compares with a value that is always zero meaning that the entire "if (0 != bus->i2c_rc)"-clause with its dev_warn can be removed from cx231xx_i2c_register.
