staging: comedi: refactor pcl724 driver to remove the forward declarations
PATCH 1/1 staging: comedi: refactor pcl724 driver to remove the 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.
