The patch titled
acpi: dock driver v4
has been removed from the -mm tree. Its filename is
acpi-dock-driver-v4.patch
This patch was probably dropped from -mm because
it has now been merged into a subsystem tree or
into Linus's tree, or because it was folded into
its parent patch in the -mm tree.
------------------------------------------------------
Subject: acpi: dock driver v4
From: Kristen Accardi <kristen.c.accardi@xxxxxxxxx>
* added dock uevents. Because this requires an acpi_device struct, if no
acpi_device struct exists, the dock_event() will create one via
acpi_bus_add() first.
