[ 04/64] regmap: Initialize `map->debugfs before regcache

From: Greg Kroah-Hartman
Date: Wed Apr 10 2013 - 19:19:11 EST


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.
