Subject: optee: fix invalid of_node_put() in optee_driver_init()
Git-commit: f044113113dd95ba73916bde10e804d3cdfa2662
Patch-mainline: v4.15-rc3
References: fate#325372
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().
