===============
[ Upstream commit 1fd24a4702d2af0ea4d5845126cf57d4d1796216 ]
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")
