I think this code will be far more useful in kernel/printk.c rather
than every device driver and subsystem rolling their own (as seems to
happen at this time).
Also see dev_dbg() and dev_printk() in include/linux/device.h.
What those macros are missing is what you have here - messages
printed or ignored depending on the value of a module variable
and/or parameter.
