ACPI / hotplug / PCI: Drop flags field from struct acpiphp_bridge
The only bridge flag used by the ACPI-based PCI hotplug (ACPIPHP) code is BRIDGE_HAS_EJ0, but it is only used by the event handling function hotplug_event() and if that flag is set, the corresponding function flag FUNC_HAS_EJ0 is set as well, so that bridge flag is redundant. For this reason, drop BRIDGE_HAS_EJ0 and all code referring to it and since it is the only bridge flag defined, drop the flags field from struct acpiphp_bridge entirely. Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com> Tested-by: Mika Westerberg <mika.westerberg@linux.intel.com>
