Subject: staging: comedi: pcmuio: 'stop_count' is always 'stop_arg'
X-Git-Tag: v3.18-rc1~130^2~491
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=8e7fed7ed760275c3e8e73e4328751fcb8f21642;p=platform%2Fkernel%2Flinux-exynos.git

staging: comedi: pcmuio: 'stop_count' is always 'stop_arg'

When the cmd->stop_src == TRIG_COUNT, the 'stop_count' is the cmd->stop_arg.
For any other stop_src the 'stop_count' is 0, which is also the cmd->stop_arg.

Simplify the 'stop_count' initialization.
