From f45cc79ae58ba78f9e7f203f1c7c203b8acb5556 Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Mon, 10 Feb 2014 15:20:34 -0700 Subject: [PATCH] staging: comedi: comedi_test: trigger sources are validated in (*do_cmdtest) The trigger sources were already validataed in the (*do_cmdtest) before the (*do_cmd) is called. Refactor the code in waveform_ai_cmd() to remove the final else which can never be reached.
