Those need to be looked at individually. You can normally see easily from
the context whether the missing log level was an accident, or the author
actually has multiple printk statements for a single line. In one case,
you would add a log level, in the other case, you can add PRINTK_CONTINUED,
or something similar. An alternative to PRINTK_CONTINUED might be a new
function, e.g. printk_continued() or similar that does not expect a log

That would mean replacing all of them, not just those that currently lack
a loglevel.
