From 57ac827c9b17f2cc2f0f86c4fd43c3597c40253c Mon Sep 17 00:00:00 2001 From: Ian Abbott Date: Wed, 20 Jan 2010 13:04:51 +0000 Subject: [PATCH] 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.
