Subject: staging: comedi: pcl3724: use comedi_request_region()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=011c131f58836cab29f896f42fca7aa03739a95c;p=linux-beck.git

staging: comedi: pcl3724: 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.
