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.
Note that strings shouldn't be split across lines since it makes it
harder to grep for them. This is one case where the 80-column limit
isn't strict, within reason.
