When did that occur?  Please reference the specific commit.
When printk_sched (now printk_deferred) was created it did not
allow KERN_<LEVEL>.

see commit 3ccf3e830615 ("printk/sched: Introduce special printk_sched() for those awkward moments")

There are many existing printk_deferred uses without KERN_<LEVEL>.
