From 2028bdc44353c8be96ae6b05813920d9989b6535 Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Tue, 9 Apr 2013 16:25:48 -0700 Subject: [PATCH] staging: comedi: ni_atmio16d: use comedi_request_region() Use comedi_request_region() to request the I/O region used by this driver. Remove the noise when the board is first attached as well as the error message when the request_region() fails, comedi_request_reqion() will output the error message if necessary.
