Subject: [PATCH 1/2] ACPI / hotplug / PCI: Rename register_slot() to acpiphp_add_context()

From: Rafael J. Wysocki <rafael.j.wysocki@...el.com>

The name of register_slot() doesn't really reflect what the function
is does, so rename it to acpiphp_add_context() and add a proper
kerneldoc comment to it.
