[PATCH 1/1] PCI: hotplug/cpcihp, fix pci device refcounting

From: Jiri Slaby
Date: Wed Jan 20 2010 - 08:16:14 EST

Stanse found an ommitted pci_dev_put on one error path in
cpcihp_generic_init. The path is taken on !dev, but also when
dev->hdr_type != PCI_HEADER_TYPE_BRIDGE. However it omits to
pci_dev_put on the latter.

As it is fine to pass NULL to pci_dev_put, put it in there
