The i2c-rcar driver currently prints an error message if the master_xfer
callback fails. However if the bus is being probed then lots of NAKs
will be generated, causing the output of a number of errors printed.
To solve this, disable the print if the error is not -EREMOTEIO.
An example of running i2cdetect:
10: i2c-rcar
e6530000.i2c: error -121 : 15
-- i2c-rcar
e6530000.i2c: error -121 : 15
-- 12 i2c-rcar
e6530000.i2c: error -121 : 15
-- i2c-rcar
e6530000.i2c: error -121 : 15
-- i2c-rcar
e6530000.i2c: error -121 : 15
-- i2c-rcar
e6530000.i2c: error -121 : 15
-- i2c-rcar
e6530000.i2c: error -121 : 15
-- i2c-rcar
e6530000.i2c: error -121 : 15
