Along with everything that Arnd said, one more thing:

This should just be deleted entirely, use ftrace if you want to see what
your kernel driver is doing.
No single driver should have special debugging macros like this, use the
kernel-wide system please.
This driver code can get a lot smaller after you make these cleanups.
Also be sure to use scripts/checkpatch.pl to remove the issues that it
points out so we don't have to say the same thing.
