Heh, ok I figured it out, the pr_debug() uses a macro for one of its
params, which internally calls WARN, which then calls printk
again...in the case of no printk, that makes the macro no_printk() try
to recursively call no_printk()...

I'll remove the WARN so there's not a printk-inside-a-printk.

thanks!
