[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. Signed-off-by: Ben Collins <bcollins@ubuntu.com> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
