3.16.7-ckt27 -stable review patch. If anyone has any objections, please let me know.

From: "Spencer E. Olson" <olsonse@xxxxxxxxx>
commit 1fd24a4702d2af0ea4d5845126cf57d4d1796216 upstream.
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")
