Commits881a8c120aandefe1ec2783corrects pci device matching in only one way; it no longer oopses/crashes, despite hotplug is not solved in these changes. Whenever pci_find_device -> pci_get_device change is performed, also pci_dev_get and pci_dev_put should be in most cases called to properly handle hotplug. This patch does exactly this thing -- increase refcount to let kernel know, that we are using this piece of HW just now. It affects moxa and rio char drivers.
