From fbca05d601a94d16912613d119f5b672a75a587f Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Fri, 22 Mar 2013 09:54:16 -0700 Subject: [PATCH] staging: comedi: ni_labpc: cleanup labpc_counter_load() usage For aesthetic reasons, move the labpc_counter_load() function so it's by the labpc_counter_set_mode() function. Update all the labpc_counter_load() calls so that the I8254_MODE* enums are used instead of the open coded values.
