From 48cf60d1645140ab07f5272ca89a0bd8130f8365 Mon Sep 17 00:00:00 2001 From: Chase Southwood Date: Fri, 7 Mar 2014 02:37:17 -0600 Subject: [PATCH] Staging: comedi: addi-data: tidy up digital output register map defines in hwdrv_apci1564.c This patch fixes the register map defines for the digital output registers such that they are all the real offsets to each register, rather than a mix of real offsets and adders to those offsets. Further, some of the old defines were being used incorrectly in the i_APCI1564_Reset() function. Upon swapping the old defines out for the new ones in this function, their use has been corrected.
