From f55354b0a8a3c6d3e5fc64b3da37510711aaf352 Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Wed, 18 Jul 2012 18:56:49 -0700 Subject: [PATCH] staging: comedi: daqboard2000: remove 'got_regions' from private data The 'got_regions' variable in the private data is used as a flag for the detach to know if the pci device has been enabled. Typically the dev->iobase variable is used to indicate this in all the other comedi drivers. Do the same here for consistancy.
