From 4d76714b03e6f69aee316a2fa467811796076607 Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Fri, 4 May 2012 15:39:55 -0700 Subject: [PATCH] staging: comedi: refactor me_daq 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.
