If an i2c access through i2c-cros-ec-tunnel returns an error, the following log message is seen on the console. cros-ec-i2c-tunnel ff200000.spi:ec@0:i2c-tunnel: Error parsing EC i2c message -121 This can happen a lot if, for example, the i2c-detect command is executed. Since it is perfectly normal for an i2c controller to report an error, drop the message. Also, report -ENXIO instead of -EREMOTEIO if the access error is due to NAK from the device, and return -EIO instead of -EREMOTEIO for other errors, as suggested in Documentation/i2c/fault-codes.
