fpga: stratix10-soc: fix wrong of_node_put() in init function

Nicolas Saenz Julienne · gregkh · commit 32a66374487b · 2019-01-31T16:19:48.000+01:00
After finding a "firmware" dt node stratix10 tries to match it's compatible string with it. To do so it's calling of_find_matching_node() which already takes care of decreasing the refcount on the "firmware" node. We are then incorrectly decreasing the refcount on that node again. This patch removes the unwarranted call to of_node_put().
