From e9720fd2b8fa65e4449c1d57b114dd4f6cc0a676 Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Tue, 9 Apr 2013 16:30:29 -0700 Subject: [PATCH] staging: comedi: 8255: use __comedi_request_region() Use __comedi_request_region() to request the I/O regions used by this driver. Remove the error message when the request_region() fails, comedi_request_reqion() will output the error message if necessary.
