I don't know.

Last I recall via searching emails, Alan Jenkins was going to do
something with it. (I've added his old email to this reply, but
I doubt still works)

I remember checking whether or not the removing the return value
reduced the code size on x86 (it did not), and forgot about it.

I don't know if removing the printk return value reduces overall
image size in any arch, so I didn't pursue it.
