Ick, no, never put #ifdef in .c code if you can help it.  For stuff like
this, just rely on the dynamic debug core and use the pr_debug and
dev_dbg() calls, like the driver is doing, so all should be fine.

This should be moved to use dev_dbg(), along with the other calls to
this function in this file.
