Subject: [PATCH 1/3] fpga: stratix10-soc: fix wrong of_node_put() in init function
Date: Thu, 24 Jan 2019 14:45:52 -0600	[thread overview]
Message-ID: <> (raw)
In-Reply-To: <>

From: Nicolas Saenz Julienne <>

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

This patch removes the unwarranted call to of_node_put().
