Subject: [PATCH] staging: comedi: refactor the acl7225b driver to remove the forward declarations
Move the module_init/module_exit routines and the associated
struct comedi_driver and struct boardtype variables to the end
of the source. This is more typical of how other drivers are
written and removes the need to the forward declarations.
