Look at trace_printk in fs/ext4/inline.c

It's in a section guarded by a CONFIG_FOO_DEBUG
block. Is the use there an error? Perhaps not
and I think it better if checkpatch ERROR messages
are more definitive.

I'm not much of a fan of that one, nor of most
of the ERROR uses in checkpatch actually.

I think it might be better if all of the checkpatch
whitespace/style related messages were WARN not ERROR.
