From fca7c1d753504a0679e4a9033382caa25259c9ed Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Thu, 19 Dec 2013 16:31:55 -0700 Subject: [PATCH] staging: comedi: ni_tio: use a local var for the 'counter_index' Use a local variable for the 'counter->counter_index' to help shorten the long lines and ugly line breaks.
