Subject: [PATCH] Char: correct pci_get_device changes

Commits 881a8c120acf7ec09c90289e2996b7c70f51e996 and
efe1ec27837d6639eae82e1f5876910ba6433c3f corrects 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.
