Subject: [PATCH] staging: comedi: refactor pcl818 driver to remove forward declarations
Move the module_init/module_exit routines and the associated
struct comedi_driver and other variables to the end of the source.
This is more typical of how other drivers are written and removes
the need for the forward declarations.

There are still some forward declarations in this file but fixing them
in this patch makes in to messy for review.
