From 958c59891a5205906f113e3f97ebc71026ca7de0 Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Tue, 15 May 2012 13:12:53 -0700 Subject: [PATCH] staging: comedi: refactor adv_pci1710 driver and use module_comedi_pci_driver Move the module_init/module_exit routines and the associated struct comedi_drive and struct pci_driver to the end of the source. This is more typical of how other drivers are written and removes the need for the forward declarations. Convert the driver to use the module_comedi_pci_driver() macro which makes the code smaller and a bit simpler.
