But pr_debug() is the "standard" way to enable/disable debugging
messages, so I'd really like to see that be used here.

Even better, this is a tty device, so it should be using dev_dbg(),
which gives us tons of good information built-in for the tty and can
properly be parsed by userspace tools to know exactly what device caused
what message at what point in time.

So I'll take this for now, but moving it to use dev_dbg() would be best
eventually.

thanks,
