[PATCH 3.13 064/172] batman-adv: fix TT-TVLV parsing on OGM reception

[Greg Kroah-Hartman]

3.13-stable review patch.  If anyone has any objections, please let me know.

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

From: Antonio Quartulli <antonio@xxxxxxxxxxxxxx>

[ Upstream commit e889241f45f9cecbc84a6ffed577083ab52e62ee ]

When accessing a TT-TVLV container in the OGM RX path
the variable pointing to the list of changes to apply is
altered by mistake.

This makes the TT component read data at the wrong position
in the OGM packet buffer.

Fix it by removing the bogus pointer alteration.
