From 32a66374487bbd78115747f0084cea5e8fca4c80 Mon Sep 17 00:00:00 2001 From: Nicolas Saenz Julienne Date: Sat, 26 Jan 2019 10:38:29 -0600 Subject: fpga: stratix10-soc: fix wrong of_node_put() in init function 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().
