From 7b650090398c4e1508a1c4fd38bb744ecab584fa Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Tue, 9 Apr 2013 16:27:03 -0700 Subject: [PATCH] staging: comedi: pcmda12: 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.
