Subject: Staging: comedi: pcl818: Remove unneeded chanlist_len check
X-Git-Url: http://git.mmlx.us/?a=commitdiff_plain;h=57ac827c9b17f2cc2f0f86c4fd43c3597c40253c;p=linux-edison.git

Staging: comedi: pcl818: Remove unneeded chanlist_len check

For AI command testing, the driver does not need to range-check the
length of the channel list as the comedi core has already checked it.
