One may notice that dev_printk(KERN_DEBUG ...) is *not* an equivalent

And currently it will be the only message in the I²C core in some
configurations that got printed under above conditions.

Moving to dev_dbg() will hide it in the configurations where Dynamic Debug
is enabled and hence align with all other debug messages in the I²C core..

OK in general.

+	bool error_or_debug = true;

A bool having "or" in the name is quite confusing: "do you want this or
that" - "yes!" :) What about "is_error_level"?
