From 1fd24a4702d2af0ea4d5845126cf57d4d1796216 Mon Sep 17 00:00:00 2001 From: "Spencer E. Olson" Date: Tue, 12 Jan 2016 10:33:18 -0700 Subject: [PATCH] staging: comedi: ni_tiocmd: change mistaken use of start_src for start_arg This fixes a bug in function ni_tio_input_inttrig(). The trigger number should be compared to cmd->start_arg, not cmd->start_src. Fixes: 6a760394d7eb ("staging: comedi: ni_tiocmd: clarify the cmd->start_arg validation and use") Cc: # 3.17+ Signed-off-by: Spencer E.
