From 1b18bbb580e96af4e12788fcc1758f68a5cebf86 Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Mon, 23 Apr 2012 14:50:39 -0700 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.
