Well, it would be good to say what problem this is attempting to fix.

And while I understand the underlying concern, there is a merit in keeping
each of these messages in one line (if everything goes well), so I'm wondering
what about printing each of them in one go after the operation with a tail
depending on the result?  Like

printk(KERN_INFO "PM: Syncing filesystems ... done\n");

on success or

printk(KERN_INFO "PM: Syncing filesystems ... failed\n");

on failure?
