From: H Hartley Sweeten Date: Tue, 9 Apr 2013 23:06:58 +0000 (-0700) Subject: staging: comedi: pcl711: use comedi_request_region() X-Git-Tag: v3.10-rc1~192^2~181 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=531f4fd1fbd169b6a22efe829663e8a278b88766;p=platform%2Fkernel%2Flinux-3.10.git staging: comedi: pcl711: 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.
