From e68a83fe522a031d0799e8cad8c06f5d653c7782 Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Mon, 23 Apr 2012 15:43:22 -0700 Subject: [PATCH] staging: comedi: refactor adl_pci9111 driver to remove forward declarations Move the module_init/module_exit routines and variables to the end of the source as is more typically done with other drivers. Then rearrange the attach/detach and probe/remove functions, this removes the need for all the forward declarations.
