i2c_transfer returns negative errno on error and number of messages processed on success. Just returning this value would give a poor interface as it is not obvious that you must compare with 2 after reading 1 or n bytes and with 1 after writing 1 byte to determine if it was successful. To avoid this error prone interface convert the error code of a successful read/write to zero and all other non-negative values to an negative error code. This fixes a regression introduced by via: Rationalize vt1636 detection which resulted in no longer detecting a VT1636 chip and therefore has broken the output in configurations which contain this chip.
