From 236788fcf0ecead56090d7d061f51974bdfed4a0 Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Fri, 27 Apr 2012 17:35:22 -0700 Subject: [PATCH] staging: comedi: refactor ke_counter 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.
