I get warnings about 'device' possibly being used uninitialised. While
I can deduce this is not true, it seems that GCC can't. This patch
changes `check_slot' to return device on success and -1 on error, which
shuts GCC up.

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.

Detect all physical PCI slots as described by ACPI, and create entries in
/sys/bus/pci/slots/.
Not all physical slots are hotpluggable, and the acpiphp module does not
detect them. Now we know the physical PCI geography of our system, without
caring about hotplug.
