- uml-drivers-get-release-methods.patch removed from -mm tree

[akpm]

The patch titled
     uml: drivers get release methods
has been removed from the -mm tree.  Its filename was
     uml-drivers-get-release-methods.patch

This patch was dropped because it was merged into mainline or a subsystem tree

------------------------------------------------------
Subject: uml: drivers get release methods
From: Jeff Dike <jdike@addtoit.com>

Define release methods for the ubd and net drivers.  They contain as much of
the remove methods as make sense.  All error checking must have already been
done as well as anything else that might be holding a reference on the device
kobject.
