I think Marek has a good point here.  It was an oversight that this
"private" DEBUG_ stuff slipped into mainline.  This should never have
happened.  We tried hard to get rid of such conditionally compiled
code for debug() with the rest of the code, so we should not start
re-adding all this again.

Sorry, but I object.

At the moment, only include/usb/s3c_udc.h defines this, i. e. it is
not a generally usable feature anyway.  In anyu case, this
implementation needs to get fixed.  See the code for the debug()
implementation for an example.

Instead of defining your own set of private macros, you can use
debug_cond() instead - this works without #ifdef's.

Thanks.

Best regards,

Wolfgang Denk
