From e25ef744460ca114c9f4cd5178932135c760f456 Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Thu, 19 Dec 2013 16:31:35 -0700 Subject: [PATCH] staging: comedi: ni_tio_internal.h: replace NITIO_Gi_Command_Reg() The "Command" registers are sequential in the enum ni_gpct_register. Replace this inline CamelCase function with a simple define.
