From 31427ad355b4f9da8100312f8aea1c33dcc5cef4 Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Tue, 9 Apr 2013 16:12:34 -0700 Subject: [PATCH] staging: comedi: pcl3730: 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. Also, remove the unnecessary 'dev->irq = 0'. This driver does not use interrupts and the comedi core has already cleared this variable.
