`pr_debug()' indeed now may generate code if DEBUG is not defined,
i.e. if CONFIG_DYNAMIC_DEBUG is enabled.
This is intented for debug infrastructure the user may want to enable later.

If you want the old behavior, you can use `pr_devel()' instead, which
only generates code if DEBUG is defined.
This is intended for debug infrastructure for developers only.

However, you used `printk(KERN_DEBUG pr_fmt()...)`, which always generates code.
I'm still not 100% sure that was intentional?
