3.8-stable review patch. If anyone has any objections, please let me know.
------------------
From: Dimitris Papastamos <dp@xxxxxxxxxxxxxxxxxxxxxxxxxxx>
commit c6432ea9cc043994d5b7dcb3ad86a087777cb40c upstream.
In the rbtree code we are exposing statistics relating to the
number of nodes/registers of the rbtree cache for each of the
devices. Ensure that `map->debugfs' has been initialized before
we attempt to initialize the debugfs entry for the rbtree cache.
