Restricted pointers ("%pK") are not meant to be used through printk().
It can unintentionally expose security sensitive, raw pointer values.

Use regular pointer formatting instead.

So really this is just a revert of 2f964780c03b ("USB: core: replace %p
with %pK"), right?

Why not express it that way, and explain _why_ it's somehow now ok to
use %p when previously it wasn't?

thanks,
