Better to keep the \n. The right fix - not only here but everywhere - would
be to convert all those into dev_info/dev_dbg/..., but this is a huge
change.

I would prefer to do such changes on a separate patch series that
will do only this kind of changes. After the conversion, the string
should finish with a \n. So, dropping it will just make the conversion
more error-prone.
