From f4d36c7a424647aa07a1bb5facd226cdf2f03151 Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Tue, 13 Nov 2012 17:59:48 -0700 Subject: [PATCH] staging: comedi: usbdux: use cfc_check_trigger_arg_*() helpers Use the new helpers in the step 3 tests of usbdux_{ai,ao}_cmdtest(). Also, remove some dev_dbg() noise.
