From d8fdaea5c9cd422f87cf0257c191e030a54d71e2 Mon Sep 17 00:00:00 2001 From: Ian Abbott Date: Thu, 24 May 2012 17:27:14 +0100 Subject: [PATCH] staging: comedi: das08: Remove forward function declarations. Moved some functions to avoid forward declarations. Moved a few other bits at the same time to keep EXPORT_SYMBOL{,_GPL}() close to the symbol being exported, and PCI table close to the code that refers to it. Changed whitespace in das08_board[] and das08_cs_board[] initializers.
