From 7d9455c5c1c3a4d274256e9205e83c3cfc646f14 Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Tue, 9 Apr 2013 16:17:01 -0700 Subject: [PATCH] staging: comedi: das6402: use comedi_request_region() Use comedi_request_region() to request the I/O region used by this driver. Remove the default iobase address (0x300) that is used when the user does not pass a base address during the "comedi_config". Comedi legacy drivers should only attach to a specified address. Remove the dev_err() message when the request_region() fails, comedi_request_reqion() will output the error message if necessary.
