[PATCH] PCI: hotplug: fix error path in pci_slot's register_slot

From: Alex Chiang
Date: Thu Jul 17 2008 - 13:13:47 EST

Juha Leppänen noticed that an error path in register_slot()
wasn't returning appropriately, leading to a condition where we
might access a kfree'ed pointer, so let's fix that.

Additionally, fix up the copyright information in the file while
we're in there.
