[RFC][PATCH 9/30] ACPI / hotplug / PCI: Drop func field from struct acpiphp_bridge

From: Rafael J. Wysocki
Date: Thu Jul 11 2013 - 20:02:40 EST


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

Since the func pointer in struct acpiphp_context can always be used
instead of the func pointer in struct acpiphp_bridge, drop the
latter.
