From ea6ff788fefcb71e08fa0b1ec82c3430053bbbc2 Mon Sep 17 00:00:00 2001 From: Chase Southwood Date: Wed, 26 Feb 2014 03:09:44 -0600 Subject: [PATCH] Staging: comedi: addi-data: clean-up variable use in hwdrv_apci035.c The variable ui_Command is as of right now being cleared to a value of zero between everytime that it writes to a port and then takes a new value from a port. Seems like this zeroing is unnecessary, so we can just remove these lines.
