[PATCH] amba: Put the device's of_node on its release

From: Pawel Moll
Date: Thu May 15 2014 - 13:07:44 EST


An amba device created from Device Tree, when released, does not
decrease of_node's reference counter.

Fixed by adding a call to of_device_node_put() on the release
path, in a similar way to what platform_device_release() is doing.
