Subject: [PATCH] Remove superfluous definition of __setup_null_param() macro.


Signed-off-by: Robert P. J. Day <rpjday@...dspring.com>

  since i apparently removed the final remaining reference to this
macro in commit f4895925976977aaeda26ee2a603a99f17db500b (thanks,
adrian), there seems to be little value in keeping this definition
around.
