[PATCH 00/02] ACPI: sysfs eject support for container

[Toshi Kani]

This patchset enables sysfs eject for ACPI scan drivers and
registers the ACPI container driver as an ACPI scan driver.
This patchset is the one I mentioned in my following reply.

I think the container driver needs to be registered as an ACPI scan
driver so that sysfs eject will continue to work for container devices,
such as ACPI0004:XX/eject.  Since the container driver does not support
ACPI eject notification (and we have been discussing how system device
hot-plug should work), this sysfs eject is the only way to eject a
container device at this point.  I will send an update patchset that
applies on top of this patch.
