Subject: staging: comedi: amplc_dio200_common: 'stopcount' is always 'stop_arg'
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=06f55bb778390f5adbaa21c554505b3a4d27ff38;p=linux-beck.git

staging: comedi: amplc_dio200_common: 'stopcount' is always 'stop_arg'

When the cmd->stop_src == TRIG_COUNT, the 'stopcount' is the cmd->stop_arg. When
the stop_src == TRIG_NONE the 'stopcount' is 0, which is also the cmd->stop_arg.

Simplify the 'stopcount' initialization.
