From 4c6dacbd383c0cdd84826cb0663b6bd81eaf21fb Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Fri, 27 Apr 2012 16:21:21 -0700 Subject: [PATCH] staging: comedi: refactor pcl730 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.
