random: make it possible to enable debugging without rebuild
The module parameter that turns debugging mode (which basically means printing a few extra lines during runtime) is in '#if 0' block. Forcing everyone who would like to see how entropy is behaving on his system to rebuild seems to be a little bit too harsh. If we were concerned about speed, we could potentially turn 'debug' into a static key, but I don't think it's necessary. Drop the '#if 0' block to allow using the 'debug' parameter without rebuilding. Signed-off-by: Jiri Kosina <jkosina@suse.cz> Signed-off-by: Theodore Ts'o <tytso@mit.edu>
