From 4f456c8034ad993eb6908b8a53216bca7afe9f1f Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Fri, 20 Feb 2015 12:52:26 -0700 Subject: [PATCH] staging: comedi: ni_labpc_common: fix logically dead code issue The quick exit check of (mode == MODE_SINGLE_CHAN) results in coverity reporting a logically dead code issue in the switch code in labpc_ai_check_chanlist(). Remove the quick exit check and allow the function to handle the MODE_SINGLE_CHAN normally (the for loop will only happen 1 time and the function will return 0).
