From: H Hartley Sweeten Date: Tue, 9 Apr 2013 23:27:27 +0000 (-0700) Subject: staging: comedi: pcmmio: use comedi_request_region() X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=1bdf7c2edfd2aa00f2a016fe997eb3297a02e1e5;p=linux-beck.git staging: comedi: pcmmio: 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.
