The i2c-rcar driver currently prints an error message if the master_xfer

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:
So, after this patch i2cdetect runs fine for you? I assume you are
working with the lager/r8a7790 board? With koelsch/r8a7791, it stalls
the bus :(
It runs fine most of the time, however I've seen some issues with the
bus locking up. However it seems to be random and affects either of
bus 2 or bus 3 randomly. Once the bus does lock up then there is no
possibility of further transfers.
I am trying to put together a breakout board to get at the signals
involved as they are all pretty much only available on high-density
connectors.
I hope to have a look at this before the end of the week and see if
there is a fix for this.
