We do check it in a few places.

arch/x86_64/kernel/traps.c:                             i += printk(" "); \
arch/x86_64/kernel/traps.c:                     i += printk(" <%s> ", id);
arch/x86_64/kernel/traps.c:                     i += printk(" <EOE> ");
arch/x86_64/kernel/traps.c:                             i += printk(" <IRQ> ");
arch/x86_64/kernel/traps.c:                             i += printk(" <EOI> ");
drivers/char/mem.c:             ret = printk("%s", tmp);
