This changes the action of the system. By default:
  printk(KERN_DEBUG "foo\n");
is enabled all the time and prints to log with debug level.

But your version
  pr_debug("foo\n");
defaults to being dropped until the system is built with dynamic
debug, and that particular debug instance is enabled.

Since these are all useful, but low priority messages, not I
don't think disabling them by default is such a great idea now.
