Kdoc describes the retval in i2c_transfer. 2136 * i2c_transfer - execute a single or combined I2C message 2137 * @adap: Handle to I2C bus 2138 * @msgs: One or more messages to execute before STOP is issued to 2139 * terminate the operation; each message begins with a START. 2140 * @num: Number of messages to be executed. 2141 * 2142 * Returns negative errno, else the number of messages executed.
