From: H Hartley Sweeten Date: Tue, 9 Apr 2013 23:28:06 +0000 (-0700) Subject: staging: comedi: pcmuio: use comedi_request_region() X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=35626c2efecd6dad6ef67124ae2604385b717ed7;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git staging: comedi: pcmuio: 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.
