Understood. For checkpatch, there only is warnings (of various types)
and I was referring to the guessing you mentioned. So if we see that a
call has no new line and the following one isn't a KERN_CONT, then based
on whether there's a space or not we potentially could have one of two
warnings:

WARNING: Log messages should end in a new line (\n)

or

WARNING: Given that your log message ends in a space and not a new line,
did you maybe mean to put a KERN_CONT or pr_cont somewhere in there?? By
the way, though, KERN_CONT use is discouraged and will create its own
warning when you fix it.
