From 87d47d0547631e059c308b392cd2423fe9248c93 Mon Sep 17 00:00:00 2001 From: Ben Collins Date: Sat, 17 Dec 2005 18:39:23 -0800 Subject: [PATCH] i2o: Do not disable pci device when it's in use When dpt_i2o is loaded first, i2o being loaded would cause it to call pci_device_disable, thus breaking dpt_i2o's use of the device. Based on similar usage of pci_disable_device in other drivers.
