Subject: [PATCH] clk: dove: fix refcount leak in dove_clk_init()
Date: Wed, 26 Dec 2018 08:50:13 -0500	[thread overview]
Message-ID: <20181226135013.5580-1-tiny.windzz@gmail.com> (raw)

The of_find_compatible_node() returns a node pointer with refcount
incremented, but there is the lack of use of the of_node_put() when
done. Add the missing of_node_put() to release the refcount.
