From 8f87b832dea11dd00f6a30aaaf934c5c93556cfe Mon Sep 17 00:00:00 2001 From: Ian Abbott Date: Wed, 20 Jan 2010 13:04:48 +0000 Subject: [PATCH] Staging: comedi: adv_pci1710: 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.
