From 7d62b548ded7a5540ecd89fb38d0dab876aec78f Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Tue, 9 Sep 2014 13:05:44 -0700 Subject: [PATCH] staging: comedi: adl_pci9118: rename setup_channel_list() Rename this function so it has namespace associated with the driver. Also, this function always succeeds. Change the return type to void and remove the unnecessary error handling by the callers.
