Nice, but one issue:

That should not be an issue here.  debug_assertions is something
independent of dev_dbg() calls.  You made this a Rust-only thing, that
doesn't tie properly into the existing dynamic printk functionality by
having yet-another-way to turn this on/off, right?

So just remove the check please.

And if you want to send this as a single patch after fixing this, I'll
be glad to add it to the tree now, as it's "obviously" correct :)
