4.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jens Wiklander <jens.wiklander@linaro.org>
commit f044113113dd95ba73916bde10e804d3cdfa2662 upstream.
The first node supplied to of_find_matching_node() has its reference counter decreased as part of call to that function. In optee_driver_init() after calling of_find_matching_node() it's invalid to call of_node_put() on the supplied node again.
So remove the invalid call to of_node_put().
