[akpm]

The patch titled
     mips: pmag-ba-fb: Convert to the driver model
has been removed from the -mm tree.  Its filename was
     mips-pmag-ba-fb-convert-to-the-driver-model.patch

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

------------------------------------------------------
Subject: mips: pmag-ba-fb: Convert to the driver model
From: "Maciej W. Rozycki" <macro@linux-mips.org>

This is a set of changes to convert the driver to the driver model.  As a
side-effect the driver now supports building as a module.
