From 5950ae518f0bf9affbbb4b2178c27e516e4cacc5 Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Tue, 9 Apr 2013 16:31:07 -0700 Subject: [PATCH] staging: comedi: das16m1: use __comedi_request_region() Use __comedi_request_region() to request the additional I/O region used by this driver. Remove the error message when the request_region() fails, comedi_request_reqion() will output the error message if necessary.
