From 7cc054d0b1ff4cc96f43101fee9bcec21c725c32 Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Wed, 23 Apr 2014 16:07:01 -0700 Subject: [PATCH] staging: comedi: adv_pci1710: rename check_channel_list() For aesthetics, rename this function so it has namespace associated with the driver. Also, change it's parameters. The cmd->chanlist and cmd->chanlist_len are always passed, just pass the comedi_cmd pointer instead.
