Yes, just use 'dev_dbg' and you are finished.

Or pr_debug if you want to use different logging levels with your
macros.

I don't know what people really want to see.  In 6 months you will
probably only care about "debugging on or off" as the majority of the
messages only help you out when developing the driver, right?

So maybe par down some of the messages, or just live with seeing them
all, it will be easier in the end.
