[PATCH v2] staging: comedi: ni_tiocmd: change mistaken use of start_src for start_arg

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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")
