Subject: ni_tiocmd: Add missing 'break' in ni_tio_input_cmd().
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=e00f5f7e662f65ef722b90a69a1cd010472d0f5a;p=comedi.git

ni_tiocmd: Add missing 'break' in ni_tio_input_cmd().

In ni_tio_input_cmd() there is a missing 'break' for 'case TRIG_EXT'
which resulted in mite_arm_dma() being called twice.  Probably mostly
harmless.

Thanks to Dan Carpenter <dan dot carpenter at oracle dot com> for
spotting it in the "staging" sources.
