Subject: Input: twl6040-vibra - fix DT node memory management
From: H. Nikolaus Schaller <hns@goldelico.com>
commit c52c545ead97fcc2f4f8ea38f1ae3c23211e09a8 upstream.
commit e7ec014a47e4 ("Input: twl6040-vibra - update for device tree support")
made the separate vibra DT node to a subnode of the twl6040.
It now calls of_find_node_by_name() to locate the "vibra" subnode.
This function has a side effect to call of_node_put on() for the twl6040
parent node passed in as a parameter. This causes trouble later on.
Solution: we must call of_node_get() before of_find_node_by_name()
