Wouldn't it be much simpler to have an i/f as for dev_dbg() and also
run the log level check only for debug messages? And, the dev_dbg()
macro seems to have code that can be binary pached (?) to enable it if
the compile option is not set.

-Robert

#define dev_dbg(dev, format, arg...)            \
        ({ if (0) dev_printk(KERN_DEBUG, dev, format, ##arg); 0; })
