I find this type of format hard to read. I prefer a semi-colon to
separate the message from the failure reason (i.e. error code).
Besides that I don't understand why you're dropping the parentheses
around the "chip %s, offset %d", I found that easier on the eye.
I did to accommodate the 3 extra character ( %d) for string format on
that line as it was already near to 80 column.
Just did not want to split in multiple lines.
