From 60cb3b02bc74c90aaa77d1acda1eff73c8dda478 Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Thu, 18 Apr 2013 14:33:40 -0700 Subject: [PATCH] staging: comedi: amplc_dio200: use comedi_legacy_detach() The I/O region used by this driver is always requested using comedi_request_region(). The devpriv->io union is only used by the common code shared by the legacy and PCI drivers. Use the new comedi_legacy_detach() helper in the (*detach) to release the I/O region requested by this driver. That function will handle the proper sanity checking before releasing the resource.
