From 70998b990b0489dcebd2e5b75a0e0cc3fff1065e Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Tue, 9 Apr 2013 16:29:13 -0700 Subject: [PATCH] staging: comedi: multiq3: 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.
