Subject: [82/98] UBI: initialise update marker

2.6.32-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Peter Horton <zero@...onel-panic.org>

commit ff998793288b49a3b22d929bf8e56362320905ff upstream.

The in kernel copy of a volume's update marker is not initialised from the
volume table. This means that volumes where an update was unfinnished will
not be treated as "forbidden to use". This is basically that the update
functionality was broken.
