it's just a small detail - it's really not a big issue and my suggestion
should be functionally equivalent. What i meant is that with pr_debug()
you can remove the pit_debug() define altogether (and change all
pit_debug's to pr_debug). In that case all you need to do is to get the
printks is to stick this to the head of the source code file (to before
the include files):
#define DEBUG
and the pr_debug() calls turn from a NOP into a printk(KERN_DEBUG,...).
