From 7902639f8133bbc7d993d6214c2ffad009659bbe Mon Sep 17 00:00:00 2001 From: Jens Wiklander Date: Mon, 9 Oct 2017 11:11:49 +0200 Subject: [PATCH] BACKPORT: optee: fix invalid of_node_put() in optee_driver_init() 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().
