PCI hotplug: fix error path in pci_slot's register_slot
Juha Leppnen 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. Signed-off-by: Alex Chiang <achiang@hp.com> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>
