From 6d2d7ef7315cb40549baec7bb13dccfcf5162225 Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Wed, 18 Jul 2012 18:49:03 -0700 Subject: [PATCH] staging: comedi: cb_pcimdas: remove BADR0 from the private data The pci resource bar 0 address is only used as a "flag" to let the datach function know that the pci device has been enabled. Use dev->iobase in the detach instead and remove BADR0 from the private data.
